{"id":"DEBIAN-CVE-2022-49408","details":"In the Linux kernel, the following vulnerability has been resolved:  ext4: fix memory leak in parse_apply_sb_mount_options()  If processing the on-disk mount options fails after any memory was allocated in the ext4_fs_context, e.g. s_qf_names, then this memory is leaked.  Fix this by calling ext4_fc_free() instead of kfree() directly.
