Fedora 39 : kernel / kernel-headers / kernel-tools (2023-a7b89262c6)

high Nessus Plugin ID 186532

Language:

Synopsis

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

Description

The remote Fedora 39 host has packages installed that are affected by multiple vulnerabilities as referenced in the FEDORA-2023-a7b89262c6 advisory.

 - A use-after-free vulnerability in the Linux kernel's netfilter: nf_tables component can be exploited to achieve local privilege escalation. The function nft_trans_gc_catchall did not remove the catchall set element from the catchall_list when the argument sync is true, making it possible to free a catchall set element many times. We recommend upgrading past commit 93995bf4af2c5a99e2a87f0cd5ce547d31eb7630.
 (CVE-2023-6111)

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 kernel, kernel-headers and / or kernel-tools packages.
