Linux Kernel CVE-2026-43242

Upgrade the Linux kernel to patched versions: 5.10.252 or later for 5.10.x, 5.15.202 or later for 5.15.x, 6.1.165 or later for 6.1.x, 6.6.128 or later for 6.6.x, 6.12.75 or later for 6.12.x, 6.18.16 or later for 6.18.x, 6.19.6 or later for 6.19.x, or 7.0 or later. The fix applies to the soc/ti/k3-socinfo driver and is available via stable kernel branches at git.kernel.org (see references for specific commit hashes: c97c21d342838b2a7787b0f1d6ad417e85c906f6 and related backports). For systems unable to patch immediately, no effective workaround exists short of disabling the K3 SoC info driver module if not required for system operation (verify driver necessity first-it is typically loaded early for system identification). Monitor kernel memory usage and watch for memory pressure warnings on production systems; repeated memory pressure events may indicate exploitation or normal memory leak progression in unpatched systems. Verify patch installation by confirming kernel version matches patched release or by checking the presence of devm_regmap_init_mmio() usage in the k3-socinfo driver source.
