"value": "In the Linux kernel, the following vulnerability has been resolved:\n\next4: fix memory leak in parse_apply_sb_mount_options()\n\nIf processing the on-disk mount options fails after any memory was\nallocated in the ext4_fs_context, e.g. s_qf_names, then this memory is\nleaked. Fix this by calling ext4_fc_free() instead of kfree() directly.\n\nReproducer:\n\n mkfs.ext4 -F /dev/vdc\n tune2fs /dev/vdc -E mount_opts=usrjquota=file\n echo clear > /sys/kernel/debug/kmemleak\n mount /dev/vdc /vdc\n echo scan > /sys/kernel/debug/kmemleak\n sleep 5\n echo scan > /sys/kernel/debug/kmemleak\n cat /sys/kernel/debug/kmemleak"
