SUSE SLES15 Security Update : kernel RT (Live Patch 10 for SLE 15 SP5) (SUSE-SU-2024:1362-1)

high Nessus Plugin ID 193719

Language:

Synopsis

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

Description

The remote SUSE Linux SLES15 host has a package installed that is affected by multiple vulnerabilities as referenced in the SUSE-SU-2024:1362-1 advisory.

- When a router encounters an IPv6 packet too big to transmit to the next-hop, it returns an ICMP6 Packet Too Big (PTB) message to the sender. The sender caches this updated Maximum Transmission Unit (MTU) so it knows not to exceed this value when subsequently routing to the same host. (CVE-2023-52340)

- In the Linux kernel, the following vulnerability has been resolved: tomoyo: fix UAF write bug in tomoyo_write_control() Since tomoyo_write_control() updates head->write_buf when write() of long lines is requested, we need to fetch head->write_buf after head->io_sem is held. Otherwise, concurrent write() requests can cause use-after-free-write and double-free problems. (CVE-2024-26622)

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-livepatch-5_14_21-150500_13_35-rt package.
