CVE-2026-74594 sched/psi: Shut down rtpoll_timer in psi_cgroup_free()

In the Linux kernel, the following vulnerability has been resolved: sched/psi: Shut down rtpolltimer in psicgroupfree psischedulertpollwork is called locklessly from the scheduler hotpath and can race psitriggerdestroy taking down the last rtpoll trigger under rtpolltriggerlock:...

CVE-2026-74593

This CVE affects the Linux kernel 's sched_ext subsystem. The root cause is a lock ordering bug in scx_cgroup_lock(), which acquires scx_cgroup_ops_rwsem (write) before cgroup_lock(). This ordering can create a deadlock through kernfs when concurrent operations on cgroup rmdir and cpu.weight writ...

CVE-2026-74594

CVE-2026-74594 affects the Linux kernel's PSI (Pressure Stall Information) subsystem . A race condition exists between psi_schedule_rtpoll_work(), called locklessly from the scheduler hotpath, and psi_trigger_destroy(), which tears down the last rtpoll trigger under lock. The rtpoll_timer can be ...

CVE-2026-74592 ima: Instantiate file_truncate and path_truncate hooks

In the Linux kernel, the following vulnerability has been resolved: ima: Instantiate filetruncate and pathtruncate hooks Instantiate the filetruncate and pathtruncate LSM hooks to reset the action cache flags IMADONEMASK as soon as truncation is requested, so the file, based on policy, is...

CVE-2026-74592

This vulnerability affects the Linux kernel's IMA (Integrity Measurement Architecture) subsystem. The root cause is that the file_truncate and path_truncate LSM hooks were not instantiated, meaning the IMA_DONE_MASK action cache flags were not reset when a file was truncated. As a result, after t...

CVE-2026-74591

A race condition in the Linux kernel's __filemap_add_folio() function (in mm/filemap) allows a folio to be stored at an incorrect (intermediate rounded-down) xarray index. When the split-a-conflict retry path drops the lock for memory allocation and another thread resolves the conflict meanwhile,...

CVE-2026-74590

CVE-2026-74590 is a race condition in the Linux kernel's fsverity subsystem, specifically in the bpf_get_fsverity_digest() function. The BPF verifier and dynptr abstraction guarantee memory validity but not content stability; kfuncs must remain memory-safe under concurrent modifications. This fun...

CVE-2026-74589

A use-after-free vulnerability exists in the Linux kernel's BPF sockmap feature, specifically in the sk_redir handling within tcp_bpf_sendmsg_redir(). The function tcp_bpf_send_verdict() copies the psock->sk_redir pointer while holding the source socket lock but fails to take a reference for t...
