The vulnerability of the btrfs_sync_file() function in the include/trace/events/btrfs.h module of the Linux kernel allows a malicious actor to access protected information or cause service failures.

The vulnerability of the btrfssyncfile function in the include/trace/events/btrfs.h module of the Linux kernel stem from improper disabling or release of resources. Exploiting this vulnerability could allow a malicious actor to gain access to protected information or cause service failures...

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....
