Publication date: 07 Mar 2022
URL: https://advisories.mageia.org/MGASA-2022-0092.html
Type: security
Affected Mageia releases: 8
CVE: CVE-2022-0847,
     CVE-2022-25258,
     CVE-2022-25375

This kernel update is based on upstream 5.15.25 and fixes at least the
following security issues:

A vulnerability in the Linux kernel since version 5.8 due to uninitialized
variables. It enables anybody to write arbitrary data to arbitrary files,
even if the file is O_RDONLY, immutable or on a MS_RDONLY filesystem.
It can be used to inject code into arbitrary processes (CVE-2022-0847).

An issue was discovered in drivers/usb/gadget/composite.c in the Linux
kernel before 5.16.10. The USB Gadget subsystem lacks certain validation
of interface OS descriptor requests (ones with a large array index and
ones associated with NULL function pointer retrieval). Memory corruption
might occur (CVE-2022-25258).

An issue was discovered in drivers/usb/gadget/function/rndis.c in the
Linux kernel before 5.16.10. The RNDIS USB gadget lacks validation of
the size of the RNDIS_MSG_SET command. Attackers can obtain sensitive
information from kernel memory (CVE-2022-25375).

For other upstream fixes, see the referenced changelogs.
