What to do
AI-suggested
A fix for this vulnerability has been implemented in the Linux kernel by restoring the override_rlimit logic. Users should apply the relevant kernel update that includes this fix. Until patched, affected systems may experience signal delivery issues under certain conditions.
Description
CVE-2024-50271 is a vulnerability in the Linux kernel related to signal handling and resource limits. A recent change caused the RLIMIT_SIGPENDING limit to be enforced unconditionally, even when override_rlimit was set, breaking previous behavior. This can cause signal delivery failures, such as SIGSEGV signals not being delivered with full information, leading to application crashes and unpredictable behavior. The issue particularly affects processes hitting the signal queue limit, preventing proper fault handling. The fix restores the override_rlimit logic to skip the limit check when set.
