Description OSIDB Bzimport 2025-12-16 14:02:25 UTC 
In the Linux kernel, the following vulnerability has been resolved:

fs: ext4: change GFP_KERNEL to GFP_NOFS to avoid deadlock

The parent function ext4_xattr_inode_lookup_create already uses GFP_NOFS for memory alloction, so the function ext4_xattr_inode_cache_find should use same gfp_flag.
