In the Linux kernel, the following vulnerability has been resolved:
erofs: fix wrong kunmap when using LZMA on HIGHMEM platforms
As the call trace shown, the root cause is kunmap incorrect pages:
BUG: kernel NULL pointer dereference, address: 00000000
CPU: 1 PID: 40 Comm: kworker/u5:0 Not tainted 6.2.0-rc5 #4
Workqueue: erofs_worker z_erofs_decompressqueue_work

---[ end trace 0000000000000000 ]---
The bug is trivial and should be fixed now. It has no impact on
!HIGHMEM platforms.
