CVE-2026-46253

A flaw was found in the Linux kernel's pstore/ram component. This vulnerability, a heap buffer overflow, occurs when the system attempts to save old persistent RAM logs and the buffer size changes, leading to an out-of-bounds write. While the conditions for exploitation are extremely difficult to...
