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-2021:2198-1 advisory.

This update for the Linux Kernel 5.3.18-57 fixes several issues.

The following issues were fixed:

- CVE-2021-3489: Fixed an issue where the eBPF RINGBUF bpf_ringbuf_reserve did not check that the allocated size was smaller than the ringbuf size (bsc#1185640).
- CVE-2021-3490: Fixed an issue where the eBPF ALU32 bounds tracking for bitwise ops (AND, OR and XOR) did not update the 32-bit bounds (bsc#1185641).
- CVE-2021-33034: Fixed a use-after-free when destroying an hci_chan. This could lead to writing an arbitrary values (bsc#1186111).
- CVE-2021-32399: Fixed a race condition when removing the HCI controller (bsc#1184611).
- CVE-2020-36322: Fixed an issue was discovered in FUSE filesystem implementation which could have caused a system crash (bsc#1184211).
- CVE-2021-29154: Fixed incorrect computation of branch displacements, allowing arbitrary code execution (bsc#1184391).
- CVE-2021-28660: Fixed an out of bounds write in rtw_wx_set_scan (bsc#1183593).
- Fixed a data loss/data corruption that occurs if there is a write error on an md/raid array (bsc#1185847).

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.

Solution

Update the affected kernel-livepatch-5_3_18-57-default package.
