CVE-2023-1192 (opens in a new tab)Amendment
The Rocky-Linux security team deemed this advisory irrelevant for Rocky-Linux:9.
NVD Description
Note: Versions mentioned in the description apply only to the upstream kernel-64k-debug-modules-core package and not the kernel-64k-debug-modules-core package as distributed by Rocky-Linux.
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.
