A flaw was found in the Linux kernel's ext4 filesystem component. A local user could potentially trigger a deadlock due to inconsistent memory allocation flags in the ext4_xattr_inode_cache_find function, which could lead to a Denial of Service (DoS). However, this CVE has been rejected by the assigning CNA.

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.
