In the Linux kernel, the following vulnerability has been resolved: net/atm: fix slab-out-of-bounds read in vccsetsockopt vccsetsockopt contained an ineffective optlen check: if SOLEVELMATCHoptname, level && optlen != SOSIZEoptname return -EINVAL; If SOLEVELMATCHoptname, level evaluated to false...
CVE-2026-74689
A slab-out-of-bounds read vulnerability in the Linux kernel's ATM (Asynchronous Transfer Mode) network protocol, specifically in vcc_setsockopt(). The root cause is an ineffective optlen check: when __SO_LEVEL_MATCH evaluates to false, the length validation is short-circuited and bypassed. Additi...

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-2026-74590 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...
