https://access.redhat.com/errata/RHSA-2026:23244
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/4.19/html/release_notes/
Security Fix(es):
* libcap: libcap: Privilege escalation via TOCTOU race condition in cap_set_file() (CVE-2026-4878)
* jq: out-of-bounds read in jv_parse_sized() on error formatting for non-NUL-terminated buffers (CVE-2026-39979)
* jq: jq: Denial of Service via crafted JSON object causing hash collisions (CVE-2026-40164)
* rsync: Rsync: Use-after-free vulnerability in extended attribute handling (CVE-2026-41035)
* kernel: "Fragnesia" is a variant of Dirty Frag vulnerability in the ESP/XFRM leading to Local Privilege Escalation (LPE) vulnerability in the Linux kernel (CVE-2026-46300)
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 4.19 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/4.19/html-single/updating_clusters/index#updating-cluster-cli.

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 jq, a command line JSON processor, specifically in the libjq API. Parsing a malformed JSON input from a non-NUL-terminated buffer using the `jv_parse_sized` function can cause an out-of-bounds read, resulting in an application crash and a possible memory disclosure within the error message generated by the parser.

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.

Threats
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.

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.
