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...
