Sushma Venkatesh Reddy discovered a missing GPU TLB flush in the
i915 driver, resulting in denial of service or privilege escalation.

CVE-2022-0435

networking module for the Transparent Inter-Process Communication
(TIPC) protocol, resulting in denial of service or potentially the
execution of arbitrary code.

CVE-2022-0516

It was discovered that an insufficient check in the KVM subsystem
for s390x could allow unauthorized memory read or write access.

CVE-2022-0847

flags. An attacker can take advantage of this flaw for local
privilege escalation.

CVE-2022-22942

VMware Virtual GPU driver (vmwgfx) could result in information leak
or privilege escalation.

CVE-2022-24448

Lyu Tao reported a flaw in the NFS implementation in the Linux
kernel when handling requests to open a directory on a regular file,
which could result in a information leak.

CVE-2022-24959

A memory leak was discovered in the yam_siocdevprivate() function of
the YAM driver for AX.25, which could result in denial of service.

CVE-2022-25258

Szymon Heidrich reported the USB Gadget subsystem lacks certain
validation of interface OS descriptor requests, resulting in memory
corruption.

CVE-2022-25375

Szymon Heidrich reported that the RNDIS USB gadget lacks validation
of the size of the RNDIS_MSG_SET command, resulting in information
leak from kernel memory.

For the stable distribution (bullseye), these problems have been fixed in
version 5.10.92-2.

We recommend that you upgrade your linux packages.
