[USN-6462-2] Linux kernel (IoT) vulnerabilities

Severity Medium
Affected Packages 13
CVEs 4
Info Packages Vulnerabilities

Several security issues were fixed in the Linux kernel.

Seth Jenkins discovered that the Linux kernel did not properly perform
address randomization for a per-cpu memory management structure. A local
attacker could use this to expose sensitive information (kernel memory) or
in conjunction with another kernel vulnerability. (CVE-2023-0597)

Yu Hao and Weiteng Chen discovered that the Bluetooth HCI UART driver in
the Linux kernel contained a race condition, leading to a null pointer
dereference vulnerability. A local attacker could use this to cause a
denial of service (system crash). (CVE-2023-31083)

Lin Ma discovered that the Netlink Transformation (XFRM) subsystem in the
Linux kernel contained a null pointer dereference vulnerability in some
situations. A local privileged attacker could use this to cause a denial of
service (system crash). (CVE-2023-3772)

It was discovered that the Siano USB MDTV receiver device driver in the
Linux kernel did not properly handle device initialization failures in
certain situations, leading to a use-after-free vulnerability. A physically
proximate attacker could use this cause a denial of service (system crash).
(CVE-2023-4132)
