CVE-2022-50849

In the Linux kernel, the following vulnerability has been resolved: pstore: Avoid kcore oops by vmaping with VMIOREMAP An oops can be induced by running 'cat /proc/kcore /dev/null' on devices using pstore with the ram backend because kmapatomic assumes lowmem pages are accessible with va. Unable ...

CVE-2022-50849

CVE-2022-50849: In the Linux kernel, pstore ram-backend backends can trigger an oops when reading /proc/kcore due to kmap_atomic() assuming lowmem pages are addressable via __va(). The bug arises when vmap() is used without mapping the ramoops lowmem pages; read_kcore and aligned_vread can pass a...
