CVE-2026-89485

A flaw was found in the lockd component of the Linux kernel. This use-after-free vulnerability occurs in the nlmtraversefiles function when a file's memory is prematurely released while an iterator still holds a pointer to it. A remote attacker could potentially exploit this to cause system...

kernel: sched/psi: fix race between file release and pressure write

A flaw was found in the Linux kernel's Pressure Stall Information PSI subsystem. A race condition exists between the file release and pressure write operations, specifically concerning the priv member of struct kernfsopenfile. This can lead to a use-after-free vulnerability or a NULL dereference,...
