Synopsis

The remote SUSE host is missing one or more security updates.

Description

The remote SUSE Linux SLES12 host has a package installed that is affected by multiple vulnerabilities as referenced in the SUSE-SU-2023:1640-1 advisory.

- A use after free vulnerability exists in the ALSA PCM package in the Linux Kernel.
SNDRV_CTL_IOCTL_ELEM_{READ|WRITE}32 is missing locks that can be used in a use-after-free that can result in a priviledge escalation to gain ring0 access from the system user. We recommend upgrading past commit 56b88b50565cd8b946a2d00b0c83927b7ebb055e (CVE-2023-0266)

- In the Linux kernel before 6.1.13, there is a double free in net/mpls/af_mpls.c upon an allocation failure (for registering the sysctl table under a new location) during the renaming of a device. (CVE-2023-26545)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected kgraft-patch-4_12_14-122_147-default package.
