  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nxfs: fix ilock leak on error in xfs_dq_get_next_id\n\nxfs_dq_get_next_id() takes the quota inode ILOCK before calling\nxfs_iread_extents().  If xfs_iread_extents() fails, the function returns\nimmediately without releasing the lock, leaking the quota inode ILOCK.\nThis can leave the quota inode locked and cause subsequent quota\noperations to hang.\n\nFix this by jumping to a common unlock path on error instead of returning\ndirectly.",
