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: erofsworker zerofsdecompressqueuework EIP: zerofslzmadecompress+0x34b/0x8ac zerofsdecompress+0x12/0x14 zerofsdecompressqueue+0x7e7/0xb1c zerofsdecompressqueuework+0x32/0x60 processonework+0x24b/0x4d8 ? processonework+0x1a4/0x4d8 workerthread+0x14c/0x3fc kthread+0xe6/0x10c ? rescuerthread+0x358/0x358 ? kthreadcompleteandexit+0x18/0x18 retfromfork+0x1c/0x28 ---[ end trace 0000000000000000 ]---
The bug is trivial and should be fixed now. It has no impact on !HIGHMEM platforms.
