CVE-2022-49064

CVE-2022-49064 affects the Linux kernel's cachefiles code. The issue is an in-use flag leakage in error paths: in cachefiles_open_file(), an in-use flag could leak and cause the system to log “Inode already in use” on subsequent lookups; in cachefiles_create_tmpfile() this leakage could occur wit...
