CVE-2025-68261

CVE-2025-68261 affects the Linux kernel’s ext4 filesystem. The fix adds i_data_sem protection to ext4_destroy_inline_data_nolock() to close a race between destroying inline data and block mapping. Without protection, ext4_ind_map_blocks() may receive an inode with EXT4_INODE_EXTENTS set, triggeri...

CVE-2025-68242

CVE-2025-68242 concerns the Linux kernel NFS attribute handling. The description notes that when delegated timestamps are allowed, the kernel’s nfs_setattr does not verify the inode UID against the caller’s fsuid, leading to failures in LTP tests utimes01/utime06 (the tests modify atime/mtime usi...
