CVE-2026-89766

This Linux kernel vulnerability affects the PIDFD_GET_*_NAMESPACE ioctls in pidfd_ioctl(), which perform a ptrace credentials check before handing out a namespace file descriptor. Unlike the equivalent procfs paths (proc_ns_get_link, proc_ns_readlink), the pidfd path did not hold the target task'...

CVE-2026-89752

A race condition in the Linux kernel's memory cgroup (memcg) subsystem can cause an indefinite reclaim loop when two open files concurrently update memory.max or memory.high. Because kernfs serializes operations only per open file, a first writer may continue reclaiming toward a stale target afte...
