CVE-2022-49846 is a slab out-of-bounds write vulnerability in the Linux kernel UDF filesystem implementation. The udf_find_entry() function performs an invalid memory write during directory-entry lookup. Syzbot detected the issue using KASAN, with the recorded call chain reaching the vulnerable function through udf_lookup() during a file creation/open operation. The flaw permits corruption of kernel slab memory and has been resolved upstream.
