CVE-2022-49408
Published: Feb 26, 2025

Description
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. Reproducer: mkfs.ext4 -F /dev/vdc tune2fs /dev/vdc -E mount_opts=usrjquota=file echo clear > /sys/kernel/debug/kmemleak mount /dev/vdc /vdc echo scan > /sys/kernel/debug/kmemleak sleep 5 echo scan > /sys/kernel/debug/kmemleak cat /sys/kernel/debug/kmemleak
