In the Linux kernel, the following vulnerability has been resolved:
ext4: always panic when errors=panic is specified
Before commit 014c9caa29d3 (“ext4: make ext4_abort() use
__ext4_error()”), the following series of commands would trigger a
panic:
After commit 014c9caa29d3, remounting a file system using the test
mount option “abort” will no longer trigger a panic. This commit will
restore the behaviour immediately before commit 014c9caa29d3.
(However, note that the Linux kernel’s behavior has not been
consistent; some previous kernel versions, including 5.4 and 4.19
similarly did not panic after using the mount option “abort”.)
This also makes a change to long-standing behaviour; namely, the
following series commands will now cause a panic, when previously it
did not:
However, this makes ext4’s behaviour much more consistent, so this is
a good thing.
