CVE-2023-53144
Estado: AnalizadaMedia (5.5)—
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:
The bug is trivial and should be fixed now. It has no impact on !HIGHMEM platforms.
