CVE-2026-64164

A flaw was found in the Linux kernel's btrfs filesystem tracepoints. The btrfssyncfile trace event, when called in an atomic context, attempts to perform an operation that can cause the system to sleep. This can lead to a kernel crash, resulting in a Denial of Service DoS for the affected system....

CVE-2026-63989

CVE-2026-63989 concerns the Linux kernel bridge netlink path. The issue arises because br_setport() was historically called with the bridge lock held, but br_setport processes many attributes (flags, FDB flushing, multicast, group forward mask, backup port/NHID) that do not require the bridge loc...

In the Linux kernel, the following vulnerability has been resolved: bridge: Fix sleep in atomic context in sysfs path Since the start of the git history, brportstore always acquired the bridge lock. Back then this decision made sense: The bridge lock protects the STP state of the bridge and its...

CVE-2026-63988

CVE-2026-63988 concerns a Linux kernel fix for sleeping in atomic context during sysfs path handling in bridge brport_store(). The root cause: brport_store() previously held the bridge lock for many attributes; now most attributes don’t require the lock. As a result, calling dev_set_promiscuity()...
