The remote SUSE Linux SLES15 host has a package installed that is affected by multiple vulnerabilities as referenced in the SUSE-SU-2024:2148-1 advisory.
This update for the Linux Kernel 5.3.18-150300_59_153 fixes several issues.
The following security issues were fixed:
- CVE-2021-46955: Fixed an out-of-bounds read with openvswitch, when fragmenting IPv4 packets (bsc#1220537).
- CVE-2024-26852: Fixed use-after-free in ip6_route_mpath_notify() (bsc#1223059).
- CVE-2024-26610: Fixed memory corruption in wifi/iwlwifi (bsc#1221302).
- CVE-2022-48651: Fixed an out-of-bound bug in ipvlan caused by unset skb->mac_header (bsc#1223514).
- CVE-2023-6546: Fixed a race condition in the GSM 0710 tty multiplexor via the GSMIOC_SETCONF ioctl that could lead to local privilege escalation (bsc#1222685).
- CVE-2023-6531: Fixed a use-after-free flaw due to a race problem in the unix garbage collector's deletion of SKB races with unix_stream_read_generic()on the socket that the SKB is queued on (bsc#1218487).
- CVE-2023-1829: Fixed a use-after-free vulnerability in the control index filter (tcindex) (bsc#1210619).
Tenable has extracted the preceding description block directly from the SUSE security advisory.
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
