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:
