NVD Description
Note: Versions mentioned in the description apply only to the upstream kernel-livepatch-6.1.175-219.357 package and not the kernel-livepatch-6.1.175-219.357 package as distributed by Amazon-Linux.

In the Linux kernel, the following vulnerability has been resolved:
btrfs: tracepoints: get correct superblock from dentry in event btrfs_sync_file()
If overlay is used on top of btrfs, dentry->d_sb translates to overlay's super block and fsid assignment will lead to a crash.
Use file_inode(file)->i_sb to always get btrfs_sb.
