Details

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.
