How to fix?

Upgrade Oracle:9 kernel-devel-matched to version 0:5.14.0-362.13.1.el9_3 or higher.
This issue was patched in ELSA-2023-7749.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-devel-matched package and not the kernel-devel-matched package as distributed by Oracle. See How to fix? for Oracle:9 relevant fixed versions and status.

A use-after-free vulnerability in the Linux kernel's fs/smb/client component can be exploited to achieve local privilege escalation.

In case of an error in smb3_fs_context_parse_param, ctx->password was freed but the field was not set to NULL which could lead to double free.

We recommend upgrading past commit e6e43b8aa7cd3c3af686caf0c2e11819a886d705.
