Found In Version: 10.24.33.2
Severity: Standard
Applicable for: Wind River Linux LTS 24
Component/s: Kernel
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. CVE-2026-46300 (https://access.redhat.com/security/cve/cve-2026-46300) + security bulletin (https://access.redhat.com/security/vulnerabilities/RHSB-2026-003)
