CVE-2026-72068

CVE-2026-72068 affects the Linux kernel’s posix-cpu-timers, specifically the update_rlimit_cpu() path. On 32‑bit kernels, rlim_new * NSEC_PER_SEC is computed in 32-bit space, causing truncation when rlim_new > 4 seconds and leading to an incorrect (too small) nsecs value stored in the CPU time...

CVE-2026-72067

CVE-2026-72067 affects the Linux kernel CPU hotplug path. The issue arises in cpuhp_invoke_callback() where, if one instance fails, the rollback path reuses the prior return value, which can hide the original error and make a failed transition appear successful. The fix is to keep the rollback re...

CVE-2026-72066

CVE-2026-72066 affects the Linux kernel: cpu: hotplug bound hotplug states sysfs output. The issue arises when states_show() writes CPU hotplug state names into a single sysfs buffer with sprintf(), which can overflow the PAGE_SIZE buffer when many states are registered. The documented fix is to ...
