CVE-2026-90327

A flaw was found in the Linux kernel's phonet: pep component. A local attacker could exploit an out-of-bounds write vulnerability in the pepgetsockopt function. This occurs when a getsockopt call provides an optlen smaller than sizeofint, causing the function to write a full integer beyond the...

CVE-2026-90327

CVE-2026-90327 is a memory out-of-bounds write in the Linux kernel's phonet: pep subsystem. The vulnerable function pep_getsockopt() clamps the reported length to the caller's buffer using min_t(), but then stores the value via put_user(), which unconditionally writes sizeof(int) bytes. When a ge...
