CVE-2026-46253

In Linux kernel pstore/ram, CVE-2026-46253, the vulnerability is a heap buffer overflow during persistent_ram_save_old(). If the buffer size has grown since the first allocation, the code updates old_log_size to the new size and then copies with memcpy_fromio(), risking an out-of-bounds write (an...
