CVE-2023-5345 Open this link in a new tabHow to fix?
There is no fixed version for RHEL:9 kernel-rt-debug-modules-extra.
NVD Description
Note: Versions mentioned in the description apply only to the upstream kernel-rt-debug-modules-extra package and not the kernel-rt-debug-modules-extra package as distributed by RHEL.
See How to fix? for RHEL: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.
