{"id":"DEBIAN-CVE-2023-54182","details":"In the Linux kernel, the following vulnerability has been resolved:  f2fs: fix to check readonly condition correctly  With below case, it can mount multi-device image w/ rw option, however one of secondary device is set as ro, later update will cause panic, so let's introduce f2fs_dev_is_readonly(), and check multi-devices rw status in f2fs_remount() w/ it in order to avoid such inconsistent mount status.  mkfs.f2fs -c /dev/zram1 /dev/zram0 -f blockdev --setro /dev/zram1 mount -t f2fs dev/zram0 /mnt/f2fs mount: /mnt/f2fs: WARNING: source write-protected, mounted read-only. mount -t f2fs -o remount,rw mnt/f2fs dd if=/dev/zero  of=/mnt/f2fs/file bs=1M count=8192  kernel BUG at fs/f2fs/inline.c:258!
