CVE-2023-1192

Published: 1 November 2023

A use-after-free flaw was found in smb2_is_status_io_timeout() in CIFS in the Linux Kernel. After CIFS transfers response data to a system call, there are still local variable points to the memory region, and if the system call frees it faster than CIFS uses it, CIFS will access a free memory region, leading to a denial of service.

Notes

AuthorNote
sbeattie
this affects the KSMBD subsystem, which generally should not
be used, userspace samba is the safer choice.
marking the introduction of the cifsd/ksmbd config option as
the break commit
possible duplicate of CVE-2022-48425? The fixing commit is
the same for both CVEs.
quite likely 98bea253aa28ad8be2ce565a9ca21beb4a9419e5 is
not an accurate fix for this issue.
