Linux Kernel EUVD-2026-27759

Upgrade to patched kernel versions: 5.10.252, 5.15.202, 6.1.165, 6.6.128, 6.12.75, 6.18.16, 6.19.6, or 7.0 and later depending on your stable branch, with commits available at https://git.kernel.org/stable/. For systems unable to immediately patch, disable PRUSS driver functionality via kernel command line parameter (pruss.blacklist=1 or by not loading the ti_pruss module) if PRUSS hardware acceleration is not operationally required - this eliminates the vulnerable code path entirely but loses real-time industrial communication capabilities, making it viable only for non-industrial workloads on affected SoCs. Alternatively, restrict local user accounts and enforce least-privilege access controls to minimize the pool of authenticated users who could trigger the vulnerable driver code, though this only reduces attack surface rather than eliminating the vulnerability. Review /var/log/kern.log for PRUSS driver initialization errors or kernel oops messages indicating potential exploitation attempts or natural triggering of the bug during hardware initialization.
