PT-2026-51734

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description A NULL pointer dereference exists in the smc msg event tracepoint class, which is shared by smc tx sendmsg and smc rx recvmsg. The issue occurs because the system unconditionally...

EUVD-2026-27643

In the Linux kernel, the following vulnerability has been resolved: btrfs: tracepoints: get correct superblock from dentry in event btrfssyncfile If overlay is used on top of btrfs, dentry-dsb translates to overlay's super block and fsid assignment will lead to a crash. Use fileinodefile-isb to...
