In the Linux kernel, the following vulnerability has been resolved:
rxrpc: Fix error handling in rxgk_extract_token()
Fix a missing bit of error handling in rxgk_extract_token(): in the event
that rxgk_decrypt_skb() returns -ENOMEM, it should just return that rather
than continuing on (for anything else, it generates an abort).

Summary: Several security issues were fixed in the Linux kernel.
It was discovered that some AMD processors did not properly clear data in
the floating point divider unit during speculative execution. A local
attacker could use this to expose sensitive information. (CVE-2025-54505)
It was discovered that some AMD Zen 2 processors did not properly isolate
shared resources in the operation cache. A local attacker could possibly
use this issue to corrupt instructions executed at a higher privilege

CVE-2026-46042 [HIGH] Linux kernel (OEM) vulnerabilities
Title: Linux kernel (OEM) vulnerabilities
Summary: Several security issues were fixed in the Linux kernel.
It was discovered that the Linux kernel did not properly handle shared page
fragments during socket buffer operations, collectively known as Dirty
Frag. A logic flaw existed in the XFRM ESP-in-TCP subsystem and in the
RxRPC networking subsystem when processing paged fragments. A local
attacker could use this to escalate privileges, or possibly escape a
container. (CVE-2026-43284, CVE-2026-43500, CVE-2026-45998, CVE-2026-46000)
It was discovered that a logic flaw existed in the XFRM ESP-in-TCP
subsystem in the Linux kernel when handling socket buffer fragments. This

CVE-2026-46010 [MEDIUM] CWE-253 kernel: rxrpc: Fix error handling in rxgk_extract_token()
kernel: rxrpc: Fix error handling in rxgk_extract_token()
A flaw was found in the Linux kernel's rxrpc component. Missing error handling in the rxgk_extract_token() function, specifically when rxgk_decrypt_skb() returns an out-of-memory error (-ENOMEM), could lead to an unexpected system abort. This vulnerability could allow a local attacker to cause a Denial of Service (DoS) by triggering this specific error condition.
