Title
ip6_tunnel: clear skb2->cb[] in ip4ip6_err()
Summary
In the Linux kernel, the following vulnerability has been resolved:
ip6_tunnel: clear skb2->cb[] in ip4ip6_err()
Oskar Kjos reported the following problem.
ip4ip6_err() calls icmp_send() on a cloned skb whose cb[] was written
by the IPv6 receive path as struct inet6_skb_parm. icmp_send() passes
IPCB(skb2) to __ip_options_echo(), which interprets that cb[] region
as struct inet_skb_parm (IPv4). The layouts differ: inet6_skb_parm.nhoff
at offset 14 overlaps inet_skb_parm.opt.rr, producing a non-zero rr
value. __ip_options_echo() then reads optlen from attacker-controlled
packet data at sptr[rr+1] and copies that many bytes into dopt->__data,
a fixed 40-byte stack buffer (IP_OPTIONS_DATA_FIXED_SIZE).
To fix this we clear skb2->cb[], as suggested by Oskar Kjos.
Also add minimal IPv4 header validation (version == 4, ihl >= 5).

The vulnerable code processes network packet contents in the kernel network stack.\nAC:L - Triggering is deterministic once an IPv4-over-IPv6 tunnel endpoint exists: the attacker controls the ICMPv6 error, IPv6 extension-header-derived control block state, and quoted inner IPv4 bytes used by `__ip_options_echo()`. There is no race or hard-to-influence condition.\nPR:N - The exploit packet is unauthenticated network input and does not require the attacker to have an account or capabilities on the target. Tunnel configuration requires administration, but exploitation of an already deployed tunnel endpoint does not.\nUI:N - No victim user action is required; receipt and processing of the crafted ICMPv6 packet is enough. The path is normal kernel packet handling.\nS:U - The corruption occurs inside the kernel network stack and impacts the same kernel security authority. This is not a VM escape or cross-scope boundary bypass.\nC:H - The bug is an attacker-controlled kernel stack buffer overflow in `__ip_options_echo()` via a bogus IPv4 option length copied into a fixed 40-byte buffer. Kernel memory corruption of this kind can plausibly be leveraged for high-impact information disclosure.\nI:H - The overflow copies attacker-controlled packet data onto the kernel stack and can plausibly corrupt control data or adjacent state. Under the required higher-severity rule, this supports high integrity impact.\nA:H - Even without full code execution, the kernel stack overflow can trigger an oops, panic, or other fatal corruption. The crafted packet can be sent remotely and repeatedly against a vulnerable tunnel endpoint."

A flaw was found in OpenSSH. When the `scp` command is used by a root user to download a file with the legacy protocol option (`-O`) and without preserving original file permissions (`-p`), the downloaded file can be installed with elevated privileges (setuid or setgid). This unexpected behavior could allow a malicious file to execute with higher permissions than intended, posing a security risk through potential privilege escalation.

Threats
Impact
Important
A flaw was found in the Linux kernel's IPv6 tunnel implementation. A remote attacker could exploit this flaw by sending malicious ICMPv6 error messages to cause a stack-based buffer overflow in the kernel's IPv4-over-IPv6 tunnel error handling code. This could result in a kernel crash (denial of service) or potentially allow arbitrary code execution with kernel privileges.

Threats
Impact
Low
A flaw was found in the Linux kernel's traffic control packet editing (pedit) subsystem. In tcf_pedit_act(), the copy-on-write (COW) range for skb_ensure_writable() is computed once before iterating over edit keys, but the calculation does not account for runtime header offsets added by typed keys. This can leave part of the target write region without a proper copy-on-write, leading to an out-of-bounds write that corrupts page cache memory. A local attacker with the ability to configure traffic control rules could exploit this to escalate privileges or crash the system.

"text": "This issue is classified as Important severity primarily because a low-privileged local user can achieve full privilege escalation to root without any user interaction. The attack requires local access, which prevents remote exploitation and is the primary factor keeping the rating at Important rather than Critical.\n\nExploitation requires three components to be present on the system: the `cifs` kernel module (loaded or loadable), the `cifs-utils` package with its default `cifs.spnego` request-key rule, and the ability to create unprivileged user and mount namespaces. All three must be present for the attack chain to succeed. Environments that do not use SMB/CIFS file shares or Active Directory integration are unlikely to have `cifs-utils` installed, reducing their exposure.\n\nIn OpenShift Container Platform 4, this flaw is rated Low. The default `restricted-v2` Security Context Constraint (SCC) sets `allowPrivilegeEscalation: false` on all pods, which causes the kernel to ignore setuid file bits, preventing privilege escalation. Under non-default SCCs such as `anyuid` that permit privilege escalation, the vulnerability is constrained by PID and mount namespace isolation to the container\u0027s own filesystem. An attacker would only be able to escalate privileges within the container, not on the host or across pods.",

Threats
Exploit Status
CISA: https://www.cisa.gov/known-exploited-vulnerabilities-catalog
Impact
Important
A flaw was found in the Linux kernel's IPv6 tunnel implementation. A remote attacker could exploit this flaw by sending malicious ICMPv6 error messages to cause a stack-based buffer overflow in the kernel's IPv4-over-IPv6 tunnel error handling code. This could result in a kernel crash (denial of service) or potentially allow arbitrary code execution with kernel privileges.

Threats
Impact
Critical
A flaw was found in the Linux kernel's xfrm-ESP and RxRPC subsystems. Unsafe in-place cryptographic processing of shared socket buffer fragments allows a low-privileged local attacker to corrupt page-cache contents of readable files, including sensitive system files, and gain root privileges. The xfrm-ESP variant requires unprivileged user or network namespace creation, while the RxRPC variant depends on the rxrpc module being available on the target system.

Threats
Impact
Important
A flaw was found in the Linux kernel's networking (skbuff) component. When skb_try_coalesce() attaches paged fragments, it can lose the SKBFL_SHARED_FRAG marker. This can lead to the Encapsulating Security Payload (ESP) input decrypting data in place over page-cache backed fragments, potentially resulting in data corruption.

Threats
Impact
Important
A flaw was found in the Linux kernel's XFRM ESP-in-TCP subsystem. Unsafe in-place cryptographic processing allows a low-privileged local attacker to write arbitrary bytes into the page cache of read-only files, including sensitive system files. An attacker can exploit this to overwrite privileged binaries and gain root privileges.

Threats
Impact
Important
A vulnerability was found in the Linux kernel that allows an unprivileged local user to read sensitive files normally restricted to the root user. The flaw occurs during process exit, where a brief window allows an attacker to intercept file access from a privileged process before it fully terminates. Successful exploitation may lead to the disclosure of sensitive data such as SSH host private keys or /etc/shadow contents.

Unsafe in-place cryptographic processing of shared socket buffer fragments allows a low-privileged local attacker to corrupt page-cache contents of readable files, including sensitive system files, and gain root privileges. The xfrm-ESP variant requires unprivileged user or network namespace creation, while the RxRPC variant depends on the rxrpc module being available on the target system.",

"text": "This issue is classified as Important severity primarily because a low-privileged local user can achieve full privilege escalation to root without any user interaction. The attack requires local access, which prevents remote exploitation and is the primary factor keeping the rating at Important rather than Critical.\n\nExploitation requires three components to be present on the system: the `cifs` kernel module (loaded or loadable), the `cifs-utils` package with its default `cifs.spnego` request-key rule, and the ability to create unprivileged user and mount namespaces. All three must be present for the attack chain to succeed. Environments that do not use SMB/CIFS file shares or Active Directory integration are unlikely to have `cifs-utils` installed, reducing their exposure.\n\nIn OpenShift Container Platform 4, this flaw is rated Low. The default `restricted-v2` Security Context Constraint (SCC) sets `allowPrivilegeEscalation: false` on all pods, which causes the kernel to ignore setuid file bits, preventing privilege escalation. Under non-default SCCs such as `anyuid` that permit privilege escalation, the vulnerability is constrained by PID and mount namespace isolation to the container\u0027s own filesystem. An attacker would only be able to escalate privileges within the container, not on the host or across pods.",

The flaw occurs during process exit, where a brief window allows an attacker to intercept file access from a privileged process before it fully terminates. Successful exploitation may lead to the disclosure of sensitive data such as SSH host private keys or /etc/shadow contents.",

"text": "This is an Important flaw in the Linux kernel that allows a local unprivileged attacker to read root-owned files. The vulnerability arises from a race condition during process termination, enabling a brief window where sensitive data, such as SSH host private keys or /etc/shadow contents, can be disclosed. This could lead to unauthorized access to sensitive information on affected Red Hat Enterprise Linux systems.\n\nIn OpenShift Container Platform 4, this flaw is rated Low. The default `restricted-v2` Security Context Constraint (SCC) sets `allowPrivilegeEscalation: false` on all pods, which causes the kernel to ignore setuid file bits and prevents target binaries from opening privileged files, breaking the exploit chain entirely. Under non-default SCCs such as `anyuid` that permit privilege escalation, the vulnerability is constrained by PID and mount namespace isolation to the container\u0027s own filesystem. An attacker would only be able to access root-owned files already within the container, not host or cross-pod resources. In practice, containers rarely contain sensitive root-owned files that are not already accessible to the pod user through normal means.",

A flaw was found in libcap. A local unprivileged user can exploit a Time-of-check-to-time-of-use (TOCTOU) race condition in the `cap_set_file()` function. This allows an attacker with write access to a parent directory to redirect file capability updates to an attacker-controlled file. By doing so, capabilities can be injected into or stripped from unintended executables, leading to privilege escalation.

Threats
Impact
Important
A flaw was found in OpenSSH. When the `scp` command is used by a root user to download a file with the legacy protocol option (`-O`) and without preserving original file permissions (`-p`), the downloaded file can be installed with elevated privileges (setuid or setgid). This unexpected behavior could allow a malicious file to execute with higher permissions than intended, posing a security risk through potential privilege escalation.

Threats
Impact
Important
A flaw was found in jq, a command-line JSON processor. A remote attacker could exploit this vulnerability by providing a specially crafted JSON object. This object leverages a weakness in jq's hashing algorithm, which uses a hardcoded, publicly known seed. By crafting the JSON object to cause hash collisions, an attacker can degrade the performance of JSON object hash table operations, leading to significant CPU exhaustion and a denial of service (DoS) for systems processing the malicious JSON data.

Impact
Important
A flaw was found in rsync. When rsync is configured to handle extended attributes (using the -X or --xattrs option), a remote attacker can exploit a use-after-free vulnerability. This occurs because the receive_xattr function incorrectly processes an untrusted length value during a sorting operation, leading to memory corruption. Successful exploitation can result in a denial of service, causing the rsync process to crash, and may potentially allow for arbitrary code execution.

A flaw was found in the Linux kernel's xfrm-ESP and RxRPC subsystems. Unsafe in-place cryptographic processing of shared socket buffer fragments allows a low-privileged local attacker to corrupt page-cache contents of readable files, including sensitive system files, and gain root privileges. The xfrm-ESP variant requires unprivileged user or network namespace creation, while the RxRPC variant depends on the rxrpc module being available on the target system.

A flaw was found in the Linux kernel's traffic control packet editing (pedit) subsystem. In tcf_pedit_act(), the copy-on-write (COW) range for skb_ensure_writable() is computed once before iterating over edit keys, but the calculation does not account for runtime header offsets added by typed keys. This can leave part of the target write region without a proper copy-on-write, leading to an out-of-bounds write that corrupts page cache memory. A local attacker with the ability to configure traffic control rules could exploit this to escalate privileges or crash the system.

A flaw was found in the Linux kernel's Remote Direct Memory Access (RDMA) `umad` (User Mode Access Device) component. A local user can exploit this vulnerability by manipulating input, causing an integer underflow that leads to an out-of-bounds memory write. This memory corruption can result in a denial of service (DoS) by crashing the system, and may also lead to limited information disclosure or data integrity issues.

Threats
Impact
Moderate
A flaw was found in the Linux kernel's netfilter subsystem, specifically within the `nf_conntrack_h323` module. This vulnerability occurs in the `DecodeQ931()` function when processing a zero-length value from a packet. An integer underflow during a length calculation results in a large, incorrect value being passed to a subsequent function, leading to an out-of-bounds read. This could allow an attacker to cause a denial of service or potentially disclose sensitive information.

Threats
Impact
Important
A flaw was found in the Linux kernel's netfilter component. This vulnerability occurs because the `eui64_mt6()` function, which processes IPv6 packets, does not properly validate the MAC header for all packets. Specifically, packets with a zero fragment offset could bypass an existing guard, allowing the system to attempt to access an invalid MAC header. A remote attacker could exploit this by sending specially crafted IPv6 packets, potentially causing a system crash and leading to a Denial of Service (DoS).

A flaw was found in the Linux kernel's Distributed Lock Manager (dlm) module. An attacker could send specially crafted network messages with an oversized length parameter to the dlm_dump_rsb_name() function. This lack of validation can lead to an out-of-bounds write in the dlm_search_rsb_tree() function, potentially causing a buffer overflow. This vulnerability could allow for denial of service or, in some cases, arbitrary code execution.

Threats
Impact
Important
A flaw was found in the Linux kernel's XFS filesystem. When adding extended attributes (xattrs), which are metadata associated with files, to leaf blocks, incorrect adjustments to the freemap can occur. This inconsistency allows the entries array and free space to overlap, leading to an assertion failure. A local user can exploit this to cause the filesystem to shut down, resulting in a Denial of Service (DoS).

Threats
Impact
Moderate
A flaw was found in the Linux kernel's md/bitmap component. This vulnerability involves a use-after-free race condition that occurs during array resize operations. When the `bitmap_daemon_work()` and `__bitmap_resize()` functions execute concurrently, they can access memory pages that have already been freed. This can lead to a General Protection Fault (GPF), which causes the system to crash, resulting in a denial of service.

Threats
Impact
Moderate
A flaw was found in the Linux kernel, specifically within the netfilter: xt_tcpmss module. A remote attacker could exploit this vulnerability by sending a specially crafted TCP packet. The TCP option parser does not properly validate the remaining option length, which results in an out-of-bounds read. This allows an attacker to access memory beyond the intended buffer, potentially leading to information disclosure.

Impact
Moderate
A flaw was found in the Linux kernel. A race condition exists in the TCP (Transmission Control Protocol) IPv6 (Internet Protocol version 6) socket handling, specifically within the tcp_v6_syn_recv_sock() function. This occurs because a child socket becomes visible in the TCP hash table before its IPv6-specific information is fully initialized. A remote attacker could potentially exploit this timing window, leading to an unstable system state or unexpected behavior, which may result in a denial of service (DoS).

A flaw was found in the Linux kernel's Remote Direct Memory Access (RDMA) subsystem, specifically within the `rxe` driver. An error in the `rxe_srq_from_init` function's memory management can lead to a double free vulnerability. This occurs when an attempt to copy data to user space fails, causing the same memory region to be freed twice. A local attacker could potentially exploit this flaw to cause a denial of service (DoS) by crashing the system.

"text": "A use-after-free flaw in the Linux kernel CAN raw socket implementation can occur when raw_release() frees the per-CPU ro-\u003euniq storage before RCU-deferred receive callbacks have fully drained. A local attacker able to create raw CAN sockets and trigger CAN receive activity could race socket teardown with raw_rcv() and cause a kernel crash. The likely impact is denial of service, while privilege escalation would require additional, unproven control over per-CPU memory reuse.\nThe issue appears more consistent with an RCU lifetime/race-condition bug leading primarily to denial of service, as exploitation depends on a narrow teardown race involving a percpu object rather than a generic reclaimable slab object, with no demonstrated privilege-escalation path or obvious controlled overwrite primitive in the relatively niche CAN raw socket subsystem.",

This vulnerability occurs because the `eui64_mt6()` function, which processes IPv6 packets, does not properly validate the MAC header for all packets. Specifically, packets with a zero fragment offset could bypass an existing guard, allowing the system to attempt to access an invalid MAC header.

"text": "A flaw was found in the Linux kernel\u0027s brcmfmac Wi-Fi driver. This vulnerability occurs because the driver fails to properly validate bsscfg indices in interface (IF) events. An attacker could exploit this by sending a specially crafted IF event with an invalid bsscfg index, which could lead to an out-of-bounds write or read, potentially causing a system crash and resulting in a denial of service (DoS).",

"text": "brcmfmac IF event handling validates the firmware provided ifidx but still uses the raw bsscfgidx value as an index into the driver iflist array. A malformed firmware IF event with an out of range bsscfgidx can cause an out of bounds pointer read and may lead to an invalid pointer dereference or broader memory corruption depending on how the resulting ifp is used. For the CVSS the PR:N is used in the paranoid score because a practical attacker model may involve adjacent Wi-Fi influence over FullMAC firmware events rather than a local privileged user on the host. The issue is not reachable over a normal routed IP network. It is adjacent network or device firmware mediated. Impact is at least denial of service through a kernel crash or Wi-Fi driver failure. In the paranoid case, the unchecked firmware controlled array index potentially could lead to possible confidentiality and integrity impact (but primarily only Availability impact).",

The parser may evaluate op i plus 1 while i is already the final byte of the option area, so a crafted TCP packet can trigger an out of bounds read in the netfilter match path. If the attacker can send packets through a ruleset that uses the tcpmss match, then it can trigger this bug. The issue is network reachable only on systems with an applicable xt_tcpmss or iptables rule, and it is not a generic TCP stack exposure. Impact is primarily limited confidentiality risk from a one byte out of bounds read and possible low availability impact.",

"text": "This issue is classified as Important severity primarily because a low-privileged local user can achieve full privilege escalation to root without any user interaction. The attack requires local access, which prevents remote exploitation and is the primary factor keeping the rating at Important rather than Critical.\n\nExploitation requires three components to be present on the system: the `cifs` kernel module (loaded or loadable), the `cifs-utils` package with its default `cifs.spnego` request-key rule, and the ability to create unprivileged user and mount namespaces. All three must be present for the attack chain to succeed. Environments that do not use SMB/CIFS file shares or Active Directory integration are unlikely to have `cifs-utils` installed, reducing their exposure.\n\nIn OpenShift Container Platform 4, this flaw is rated Low. The default `restricted-v2` Security Context Constraint (SCC) sets `allowPrivilegeEscalation: false` on all pods, which causes the kernel to ignore setuid file bits, preventing privilege escalation. Under non-default SCCs such as `anyuid` that permit privilege escalation, the vulnerability is constrained by PID and mount namespace isolation to the container\u0027s own filesystem. An attacker would only be able to escalate privileges within the container, not on the host or across pods.",

Red Hat Security Advisory: OpenShift Container Platform 4.22.7 bug fix and security update
Severity
Critical
Notes
Topic: Red Hat OpenShift Container Platform release 4.22.7 is now available with updates to packages and images that fix several bugs and add enhancements.
This release includes a security update for Red Hat OpenShift Container Platform 4.22.
Red Hat Product Security has rated this update as having a security impact of Critical. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.
Details: Red Hat OpenShift Container Platform is Red Hat's cloud computing Kubernetes application platform solution designed for on-premise or private cloud deployments.
This advisory contains the container images for Red Hat OpenShift Container Platform 4.22.7. See the following advisory for the RPM packages for this release:
https://access.redhat.com/errata/RHBA-2026:44229
Space precludes documenting all of the container images in this advisory. See the following Release Notes documentation, which will be updated shortly for this release, for details about these changes:
https://docs.redhat.com/en/documentation/openshift_container_platform/4.22/html/release_notes/
Security Fix(es):
* kernel: ip6_tunnel: clear skb2->cb[] in ip4ip6_err() (CVE-2026-43037)
* cifs-utils: local privilege escalation via forged cifs.spnego key description in cifs.upcall (CVE-2026-12505)
* podman: Podman: Information disclosure via malicious container image environment variables (CVE-2026-57231)
For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.
All OpenShift Container Platform 4.22 users are advised to upgrade to these updated packages and images when they are available in the appropriate release channel. To check for available updates, use the OpenShift CLI (oc) or web console. Instructions for upgrading a cluster are available at https://docs.redhat.com/en/documentation/openshift_container_platform/4.22/html-single/updating_clusters/index#updating-cluster-cli.

A flaw was found in the cifs-utils package where the cifs.upcall helper fails to securely drop its root privileges before looking up user information inside a user-controlled environment. A local, low privileged attacker can exploit this by using a crafted request_key payload to trick the root-owned helper into entering a custom environment (namespace) containing a malicious NSS module. This forces the system to load the attacker's controlled NSS Module and configuration, allowing them to execute arbitrary commands as the root user, elevating their privileges and fully compromising the system.

Threats
Impact
Important
A flaw was found in the Linux kernel's IPv6 tunnel implementation. A remote attacker could exploit this flaw by sending malicious ICMPv6 error messages to cause a stack-based buffer overflow in the kernel's IPv4-over-IPv6 tunnel error handling code. This could result in a kernel crash (denial of service) or potentially allow arbitrary code execution with kernel privileges.

Threats
Impact
Critical
A flaw was found in Podman, a tool for managing OCI containers and pods. A malicious container image can be crafted with an environment variable that has a key but no value, or an asterisk (*), to trick Podman. This vulnerability causes Podman to pass host environment variables into the container. Consequently, a malicious image could exfiltrate all Podman environment variables set in the session from which the container is launched, leading to information disclosure.

"text": "This vulnerability affects the cifs.upcall helper in cifs-utils. Red Hat Product Security has assessed this issue as an Important severity vulnerability.\n\nThe flaw occurs because cifs.upcall performs user and group resolution operations after entering attacker-controlled namespaces but before fully dropping its elevated privileges. A local attacker may abuse this behavior to influence NSS module loading and execute arbitrary code with root privileges.\n\nSuccessful exploitation requires local access to the system and several environmental conditions, including registration of the cifs.spnego key type, the presence of the cifs-utils request-key rule, and the ability to create unprivileged user namespaces. However, once these conditions are met, exploitation may allow a local user to obtain root privileges.\n\n```\n\nThe issue has been fixed by upstream in cifs-utils v7.6\n\n```",
