CVE-2025-71089

A security vulnerability was found in the Linux kernel's IOMMU Shared Virtual Addressing (SVA) implementation on x86 architecture. When SVA is enabled, the IOMMU caches kernel page table entries. Since the kernel lacks a mechanism to notify the IOMMU when kernel page table pages are freed and reallocated, the IOMMU can retain stale entries pointing to reused memory. This can lead to use-after-free or write-after-free conditions, potentially enabling arbitrary physical memory DMA access or privilege escalation.

CVE-2026-23216

A use-after-free flaw was found in the Linux kernel's iSCSI target subsystem. In the iscsit_dec_conn_usage_count() function, complete() is called while still holding the conn->conn_usage_lock spinlock. The waiting thread (such as iscsit_close_connection()) may wake up immediately and free the iscsit_conn structure before the current thread executes spin_unlock_bh(), resulting in a use-after-free when attempting to release the lock on already-freed memory.

CVE-2026-23392

A flaw was found in the Linux kernel's netfilter component, specifically within the nf_tables subsystem. An error in releasing a flowtable after an RCU (Read-Copy-Update) grace period could lead to a use-after-free vulnerability. This issue could expose the flowtable to the packet path and nfnetlink_hook control plane, potentially allowing a local attacker to cause a system crash (Denial of Service) or achieve arbitrary code execution.

CVE-2026-31685

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).

7.1 (High)


                
                  CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:H

CVE-2026-31709

A flaw was found in the Linux kernel's Server Message Block (SMB) client, specifically within the cifsacl functionality. A malicious SMB server could provide a malformed Discretionary Access Control List (DACL) that claims to contain more Access Control Entries (ACEs) than are actually present. This insufficient validation allows the kernel to read or copy data beyond the intended memory boundaries, leading to memory corruption. This could potentially result in information disclosure or a denial of service.

7.8 (High)


                
                  CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H

CVE-2026-43037

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.

8.8 (High)


                
                  CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H

CVE-2026-43038

A flaw was found in the Linux kernel's IPv6 ICMP error generation. A remote attacker could send a specially crafted IPv4 ICMP error packet with a Common Internet Protocol Security Option (CIPSO) IP option. This could lead to incorrect handling of packet control block data when generating an IPv6 ICMP error, potentially causing an out-of-bounds memory access. This memory corruption could result in information disclosure or a denial of service.

Any internet-facing host with an IPv6 TCP listener (or that merely replies with RST) exposes the vulnerable function to unauthenticated remote traffic.\nAC:H - The attacker freely supplies the transmit side of the race by sending TCP/SCTP traffic, but the `dst_dev_put()` side (netdev unregister/link-down, veth teardown, route-exception/pcpu-route destruction) is an operational event they cannot influence from the network, and escalating past a crash requires the freed `net_device`/`inet6_dev` slab object to be reallocated with attacker-useful content. This matches sibling CVE-2025-40158 and CVE-2025-40168 in the same dst_dev_rcu series.\nPR:N - SYNACK and RST generation happen with no credentials, no established session, and no local account on the target \u2014 the kernel transmits automatically on packet arrival. Even under a purely local framing, both halves of the race (IPv6 traffic plus veth create/delete and route flush) are available to any unprivileged user via `unshare -Urn`, so no real privilege is required either way.\nUI:N - Packet transmission occurs unconditionally in softirq or backlog-drain context when traffic arrives; no administrator or local user has to open, mount, configure, or click anything.\nS:U - The freed `net_device` and `inet6_dev` are kernel-internal objects and the resulting corruption stays entirely within the kernel\u0027s own security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - This is a use-after-free read of `dev-\u003ehard_header_len`/`needed_headroom` via `LL_RESERVED_SPACE()`, of `idev-\u003estats.ipv6`, and of `out-\u003ename`/`out-\u003eifindex` inside the `NF_HOOK(NF_INET_LOCAL_OUT)` traversal; once the freed slab object is reallocated the attacker can steer header-expansion sizing and the recorded egress device, yielding kernel memory disclosure and misdirected packet leakage.\nI:H - `IP6_INC_STATS(net, idev, ...)` expands to `SNMP_INC_STATS64(idev-\u003estats.ipv6, field)`, performing a 64-bit increment through a per-CPU pointer loaded from freed memory \u2014 a write primitive after reallocation \u2014 and the stale `dev` propagates into `skb-\u003edev` and the netfilter hook state, giving control over structures used for further dispatch.\nA:H - Dereferencing a freed `inet6_dev`/`net_device` on the IPv6 transmit path reliably produces a KASAN slab-use-after-free splat, oops, or panic, and because the fault is in the core TCP/SCTP egress path it takes down the entire host."

(Even in the purely local framing the netns/CAP_NET_ADMIN half is obtainable via `unshare -Urn`, so no real privilege is required either way.)\nUI:N - Transmission and forwarding happen unconditionally in softirq/process context on packet arrival; no administrator or local user has to open, mount, or click anything.\nS:U - The freed `inet6_dev` and `net_device` are kernel objects and the corruption stays within the kernel\u0027s own security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - This is a use-after-free read of `idev-\u003ecnf.disable_ipv6`, `idev-\u003estats.ipv6`, `dev-\u003ehard_header_len`/`needed_headroom`, `dev-\u003eheader_ops` and `dev-\u003eflags`; once the freed slab object is reallocated the attacker can steer header-expansion sizes and the egress device, yielding kernel memory disclosure and out-of-device packet leakage.\nI:H - `IP6_INC_STATS`/`IP6_UPD_PO_STATS` expand to `SNMP_INC_STATS64(idev-\u003estats.ipv6, field)`, performing a 64-bit increment through a per-CPU pointer loaded from freed memory \u2014 an arbitrary-write primitive after reallocation \u2014 and `neigh_output()` \u2192 `dev_queue_xmit()` makes an indirect call through `dev-\u003enetdev_ops-\u003endo_start_xmit` read from the freed `net_device`, giving control-flow hijack.\nA:H - Dereferencing a freed `inet6_dev`/`net_device` on the packet transmit path reliably oopses or panics the kernel (KASAN slab-use-after-free), and the crash is in the core IPv6 output path so it takes down the whole forwarding host."

CVE-2025-71089 (GCVE-0-2025-71089)

Title

iommu: disable SVA when CONFIG_X86 is set

Summary

In the Linux kernel, the following vulnerability has been resolved: iommu: disable SVA when CONFIG_X86 is set Patch series "Fix stale IOTLB entries for kernel address space", v7. This proposes a fix for a security vulnerability related to IOMMU Shared Virtual Addressing (SVA). In an SVA context, an IOMMU can cache kernel page table entries. When a kernel page table page is freed and reallocated for another purpose, the IOMMU might still hold stale, incorrect entries. This can be exploited to cause a use-after-free or write-after-free condition, potentially leading to privilege escalation or data corruption. This solution introduces a deferred freeing mechanism for kernel page table pages, which provides a safe window to notify the IOMMU to invalidate its caches before the page is reused. This patch (of 8): In the IOMMU Shared Virtual Addressing (SVA) context, the IOMMU hardware shares and walks the CPU's page tables. The x86 architecture maps the kernel's virtual address space into the upper portion of every process's page table. Consequently, in an SVA context, the IOMMU hardware can walk and cache kernel page table entries. The Linux kernel currently lacks a notification mechanism for kernel page table changes, specifically when page table pages are freed and reused. The IOMMU driver is only notified of changes to user virtual address mappings. This can cause the IOMMU's internal caches to retain stale entries for kernel VA. Use-After-Free (UAF) and Write-After-Free (WAF) conditions arise when kernel page table pages are freed and later reallocated. The IOMMU could misinterpret the new data as valid page table entries. The IOMMU might then walk into attacker-controlled memory, leading to arbitrary physical memory DMA access or privilege escalation. This is also a Write-After-Free issue, as the IOMMU will potentially continue to write Accessed and Dirty bits to the freed memory while attempting to walk the stale page tables. Currently, SVA contexts are unprivileged and cannot access kernel mappings. However, the IOMMU will still walk kernel-only page tables all the way down to the leaf entries, where it realizes the mapping is for the kernel and errors out. This means the IOMMU still caches these intermediate page table entries, making the described vulnerability a real concern. Disable SVA on x86 architecture until the IOMMU can receive notification to flush the paging cache before freeing the CPU kernel page table pages.

In an SVA context, an IOMMU can cache kernel\npage table entries.  When a kernel page table page is freed and\nreallocated for another purpose, the IOMMU might still hold stale,\nincorrect entries.  This can be exploited to cause a use-after-free or\nwrite-after-free condition, potentially leading to privilege escalation or\ndata corruption.\n\nThis solution introduces a deferred freeing mechanism for kernel page\ntable pages, which provides a safe window to notify the IOMMU to\ninvalidate its caches before the page is reused.\n\n\nThis patch (of 8):\n\nIn the IOMMU Shared Virtual Addressing (SVA) context, the IOMMU hardware\nshares and walks the CPU\u0027s page tables.  The x86 architecture maps the\nkernel\u0027s virtual address space into the upper portion of every process\u0027s\npage table.  Consequently, in an SVA context, the IOMMU hardware can walk\nand cache kernel page table entries.\n\nThe Linux kernel currently lacks a notification mechanism for kernel page\ntable changes, specifically when page table pages are freed and reused. \nThe IOMMU driver is only notified of changes to user virtual address\nmappings.  This can cause the IOMMU\u0027s internal caches to retain stale\nentries for kernel VA.\n\nUse-After-Free (UAF) and Write-After-Free (WAF) conditions arise when\nkernel page table pages are freed and later reallocated.  The IOMMU could\nmisinterpret the new data as valid page table entries.  The IOMMU might\nthen walk into attacker-controlled memory, leading to arbitrary physical\nmemory DMA access or privilege escalation.  This is also a\nWrite-After-Free issue, as the IOMMU will potentially continue to write\nAccessed and Dirty bits to the freed memory while attempting to walk the\nstale page tables.\n\nCurrently, SVA contexts are unprivileged and cannot access kernel\nmappings.  However, the IOMMU will still walk kernel-only page tables all\nthe way down to the leaf entries, where it realizes the mapping is for the\nkernel and errors out.  This means the IOMMU still caches these\nintermediate page table entries, making the described vulnerability a real\nconcern.\n\nDisable SVA on x86 architecture until the IOMMU can receive notification\nto flush the paging cache before freeing the CPU kernel page table pages."

CVE-2026-23216 (GCVE-0-2026-23216)

Vulnerability from cvelistv5 – Published: 2026-02-18 14:21 – Updated: 2026-06-11 17:53

Title

scsi: target: iscsi: Fix use-after-free in iscsit_dec_conn_usage_count()

Summary

In the Linux kernel, the following vulnerability has been resolved: scsi: target: iscsi: Fix use-after-free in iscsit_dec_conn_usage_count() In iscsit_dec_conn_usage_count(), the function calls complete() while holding the conn->conn_usage_lock. As soon as complete() is invoked, the waiter (such as iscsit_close_connection()) may wake up and proceed to free the iscsit_conn structure. If the waiter frees the memory before the current thread reaches spin_unlock_bh(), it results in a KASAN slab-use-after-free as the function attempts to release a lock within the already-freed connection structure. Fix this by releasing the spinlock before calling complete().

CVE-2026-23392 (GCVE-0-2026-23392)

Vulnerability from cvelistv5 – Published: 2026-03-25 10:33 – Updated: 2026-09-08 08:45

Title

netfilter: nf_tables: release flowtable after rcu grace period on error

Summary

In the Linux kernel, the following vulnerability has been resolved: netfilter: nf_tables: release flowtable after rcu grace period on error Call synchronize_rcu() after unregistering the hooks from error path, since a hook that already refers to this flowtable can be already registered, exposing this flowtable to packet path and nfnetlink_hook control plane. This error path is rare, it should only happen by reaching the maximum number hooks or by failing to set up to hardware offload, just call synchronize_rcu(). There is a check for already used device hooks by different flowtable that could result in EEXIST at this late stage. The hook parser can be updated to perform this check earlier to this error path really becomes rarely exercised. Uncovered by KASAN reported as use-after-free from nfnetlink_hook path when dumping hooks.

Severity

CVE-2026-31685 (GCVE-0-2026-31685)

Vulnerability from cvelistv5 – Published: 2026-04-25 08:47 – Updated: 2026-08-05 12:24

Title

netfilter: ip6t_eui64: reject invalid MAC header for all packets

Summary

In the Linux kernel, the following vulnerability has been resolved: netfilter: ip6t_eui64: reject invalid MAC header for all packets `eui64_mt6()` derives a modified EUI-64 from the Ethernet source address and compares it with the low 64 bits of the IPv6 source address. The existing guard only rejects an invalid MAC header when `par->fragoff != 0`. For packets with `par->fragoff == 0`, `eui64_mt6()` can still reach `eth_hdr(skb)` even when the MAC header is not valid. Fix this by removing the `par->fragoff != 0` condition so that packets with an invalid MAC header are rejected before accessing `eth_hdr(skb)`.

Severity

9.4 (Critical)

CVE-2026-31709 (GCVE-0-2026-31709)

Vulnerability from cvelistv5 – Published: 2026-05-01 13:56 – Updated: 2026-08-05 12:24

Title

smb: client: validate the whole DACL before rewriting it in cifsacl

Summary

In the Linux kernel, the following vulnerability has been resolved: smb: client: validate the whole DACL before rewriting it in cifsacl build_sec_desc() and id_mode_to_cifs_acl() derive a DACL pointer from a server-supplied dacloffset and then use the incoming ACL to rebuild the chmod/chown security descriptor. The original fix only checked that the struct smb_acl header fits before reading dacl_ptr->size or dacl_ptr->num_aces. That avoids the immediate header-field OOB read, but the rewrite helpers still walk ACEs based on pdacl->num_aces with no structural validation of the incoming DACL body. A malicious server can return a truncated DACL that still contains a header, claims one or more ACEs, and then drive replace_sids_and_copy_aces() or set_chmod_dacl() past the validated extent while they compare or copy attacker-controlled ACEs. Factor the DACL structural checks into validate_dacl(), extend them to validate each ACE against the DACL bounds, and use the shared validator before the chmod/chown rebuild paths. parse_dacl() reuses the same validator so the read-side parser and write-side rewrite paths agree on what constitutes a well-formed incoming DACL.

That avoids the immediate\nheader-field OOB read, but the rewrite helpers still walk ACEs based on\npdacl-\u003enum_aces with no structural validation of the incoming DACL body.\n\nA malicious server can return a truncated DACL that still contains a\nheader, claims one or more ACEs, and then drive\nreplace_sids_and_copy_aces() or set_chmod_dacl() past the validated\nextent while they compare or copy attacker-controlled ACEs.\n\nFactor the DACL structural checks into validate_dacl(), extend them to\nvalidate each ACE against the DACL bounds, and use the shared validator\nbefore the chmod/chown rebuild paths.  parse_dacl() reuses the same\nvalidator so the read-side parser and write-side rewrite paths agree on\nwhat constitutes a well-formed incoming DACL."

Local chmod/chown permission checks apply to the victim-side process, not to the remote attacker.\nUI:R - Exploitation requires the victim system or an automated victim workflow to mount/use the SMB share and issue metadata operations such as stat, chmod, chown, or chgrp. The server cannot trigger this parser without a client request.\nS:U - The vulnerable component and the impacted resource are the same Linux kernel security authority on the SMB client. This is not a VM escape, IOMMU bypass, or cross-authority boundary violation.\nC:H - The malformed DACL can drive out-of-bounds reads while copying ACE/SID data, and rewritten ACL data can be sent back to the malicious server. Under the required high-severity tie-break rule, this is treated as high confidentiality impact.\nI:H - The chown/chgrp rewrite path can copy attacker-influenced ACEs into a newly allocated security descriptor beyond the size derived from the declared DACL, creating kernel heap memory corruption.
