CVE-2026-80775

CVE-2026-80775 is a race condition in the Linux kernel futex subsystem, specifically in the initial allocation of mm->futex.phash.ref. The root cause is a concurrent execution scenario introduced by nested vfork : when a vfork child calls vfork again and is killed with SIGKILL, the parent and ...

Linux kernel function use-after-free? No, we need to follow rules

The vulnerability of the needfutexhashallocatedefault function in the kernel/fork.c module of the Linux operating system is related to the use of memory after it is freed. Exploiting this vulnerability could allow an attacker to compromise the confidentiality, integrity, and accessibility of the...
