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 fsverity: Fix bpf_get_fsverity_digest() dynptr assumptions
In the Linux kernel, the following vulnerability has been resolved: fsverity: Fix bpfgetfsveritydigest dynptr assumptions The BPF verifier and the dynptr abstraction ensure that the memory space referenced by a dynptr remains valid. They do not, however, provide any guarantee that the contents of...
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...

CVE-2026-74588
CVE-2026-74588 is a use-after-free in the Linux kernel's SCTP implementation. In __sctp_outq_flush_rtx(), a gap-acked chunk is moved to another transport's transmitted list via list_move_tail() without updating chunk->transport. If the original transport is freed (triggered by an ASCONF Delete...
