SUSE SLES12 / SLES15 Security Update : kernel (Live Patch 11 for SLE 12 SP5) (SUSE-SU-2021:2361-1)

high Nessus Plugin ID 151757

Language:

Synopsis

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

Description

The remote SUSE Linux SLES12 / SLES15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2021:2361-1 advisory.

- In __hidinput_change_resolution_multipliers of hid-input.c, there is a possible out of bounds write due to a heap buffer overflow. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.Product: AndroidVersions: Android kernelAndroid ID: A-173843328References: Upstream kernel (CVE-2021-0512)

- A race condition in Linux kernel SCTP sockets (net/sctp/socket.c) before 5.12-rc8 can lead to kernel privilege escalation from the context of a network service or an unprivileged process. If sctp_destroy_sock is called without sock_net(sk)->sctp.addr_wq_lock then an element is removed from the auto_asconf_splist list without any proper locking. This can be exploited by an attacker with network service privileges to escalate to root or from the context of an unprivileged user directly if a BPF_CGROUP_INET_SOCK_CREATE is attached which denies creation of some SCTP socket. (CVE-2021-23133)

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-4_12_14-197_75-default, kernel-livepatch-5_3_18-24_43-default and / or kgraft- patch-4_12_14-122_46-default packages.
