CVE-2022-49004 is a medium-severity vulnerability affecting the Linux kernel, specifically within the RISC-V architecture's handling of EFI page tables. It arises when kernel stacks are allocated in the vmalloc area, potentially causing a kernel panic due to a mismatch between the EFI page table and the kernel's current mappings. The vulnerability has a CVSS score of 5.5 (MEDIUM) with a vector of AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H, indicating a local attack vector with low complexity, requiring low privileges, and resulting in high availability impact (denial of service). There is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage surrounding this CVE.
