In the Linux kernel, the following vulnerability has been resolved: net/smc: fix sleep-inside-lock in smcsetsockopt causing local DoS A logic flaw in smcsetsockopt allows a local unprivileged user to cause a Denial of Service DoS by holding the socket lock indefinitely. The function smcsetsockopt...

CVE-2026-53274

The CVE-2026-53274 issue affects the Linux kernel net/smc implementation. A logic flaw in __smc_setsockopt() performs copy_from_sockptr() while holding lock_sock(sk), enabling a local unprivileged user to block the socket lock and cause a DoS by tying up kernel work queues, especially with shutdo...

CVE-2026-53268 : In the Linux kernel, the netfilter component “conntrack_irc” vulnerability fixes a possible out-of-bounds read that occurs when parsing fails after a command string has been matched; the correct behavior is to bail out instead of attempting to match another command. The issue is ...

EUVD-2026-39219

In the Linux kernel, the following vulnerability has been resolved: netfilter: conntrackirc: fix possible out-of-bounds read When parsing fails after we've matched the command string we should bail out instead of trying to match a different command. This helper should be deprecated, given...
