Description

In the Linux kernel, the following vulnerability has been resolved:

jfs: add check read-only before txBeginAnon() call

Added a read-only check before calling `txBeginAnon` in `extAlloc`
and `extRecord`. This prevents modification attempts on a read-only
mounted filesystem, avoiding potential errors or crashes.

Call trace:
