CVE-2022-49067

CVE-2022-49067 is about a Linux kernel issue where virt_addr_valid() incorrectly returned true for vmalloc addresses in 64-bit Book3E (and related 32-bit behavior). Investigations across multiple advisories (NVD, Red Hat, Debian OSV, Unity/NASL/Nessus plugins) describe the root cause: __pa() can ...

CVE-2022-49067

In the Linux kernel, the following vulnerability has been resolved: powerpc: Fix virtaddrvalid for 64-bit Book3E & 32-bit mpe: On 64-bit Book3E vmalloc space starts at 0x8000000000000000. Because of the way pa works we have: pa0x8000000000000000 == 0, and therefore virttopfn0x8000000000000000 == ...
