  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nima: return error early if file xattr cannot be changed\n\nDuring early boot, the filesystem is read-only and any changes\nto xattrs are not allowed. This fails in case of ext4 because\nchanging xattr starts an ext4 transaction which fails with the\nfollowing warning.\n\nWARNING: fs/ext4/ext4_jbd2.c:75 at ext4_journal_check_start+0x63/0xa0 [ext4], CPU#1: systemd-sysroot/561\nCPU: 1 UID: 0 PID: 561 Comm: systemd-sysroot Not tainted 6.19.12-1-default #1 PREEMPT(voluntary) openSUSE Tumbleweed  c2dfc3c9d9f6f1233251c5d4410574fe82a348ee\nHardware name: QEMU Standard PC (Q35 + ICH9, 2009), BIOS unknown 02/02/2022\nRIP: 0010:ext4_journal_check_start+0x63/0xa0 [ext4]\nCall Trace:\n  __ext4_journal_start_sb+0x3e/0x180 [ext4 6d025f3bc52c89a957b89a89d211fadf5e9434e1]\n  ext4_xattr_set+0x104/0x150 [ext4 6d025f3bc52c89a957b89a89d211fadf5e9434e1]\n  __vfs_setxattr+0x9a/0xd0\n  __vfs_setxattr_noperm+0x76/0x1f0\n  ima_appraise_measurement+0x23e/0xe40\n  ima_d_path+0x5a/0xd0\n  process_measurement+0xb29/0xc40\n  ? copy_from_kernel_nofault+0x21/0xe0\n  ? fscrypt_file_open+0xc0/0xe0\n  ? ext4_file_open+0x60/0x490 [ext4 6d025f3bc52c89a957b89a89d211fadf5e9434e1]\n  ? bpf_prog_31efb7c56239148b_restrict_filesystems+0xab/0x126\n  ? __bpf_prog_exit+0x23/0xd0\n  ? __bpf_tramp_exit+0xd/0x50\n  ? bpf_trampoline_6442530367+0x9f/0xea\n  ima_file_check+0x57/0x80\n  security_file_post_open+0x50/0xf0\n  path_openat+0x493/0x1650\n  do_filp_open+0xc7/0x170\n\nDetect the state of the file early and return the error.",
