CVE-2026-43124

A flaw was found in the Linux kernel's pstore ramcore component. A local attacker could exploit a vulnerability where the persistentrambuffermap function incorrectly returns success even when the underlying vmap memory mapping operation fails. This occurs if a non-zero offset is used, leading to...
