| Description: | Summary:
The remote host is missing an update for the 'linux-oem-6.1' package(s) announced via the USN-6415-1 advisory.
Vulnerability Insight:
Daniel Trujillo, Johannes Wikner, and Kaveh Razavi discovered that some AMD
processors utilising speculative execution and branch prediction may allow
unauthorised memory reads via a speculative side-channel attack. A local
attacker could use this to expose sensitive information, including kernel
memory. (CVE-2023-20569)
Ivan D Barrera, Christopher Bednarz, Mustafa Ismail, and Shiraz Saleem
discovered that the InfiniBand RDMA driver in the Linux kernel did not
properly check for zero-length STAG or MR registration. A remote attacker
could possibly use this to execute arbitrary code. (CVE-2023-25775)
It was discovered that the USB subsystem in the Linux kernel contained a
race condition while handling device descriptors in certain situations,
leading to a out-of-bounds read vulnerability. A local attacker could
possibly use this to cause a denial of service (system crash).
(CVE-2023-37453)
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)
Lin Ma discovered that the Netlink Transformation (XFRM) subsystem in the
Linux kernel did not properly initialize a policy data structure, leading
to an out-of-bounds vulnerability. A local privileged attacker could use
this to cause a denial of service (system crash) or possibly expose
sensitive information (kernel memory). (CVE-2023-3773)
Kyle Zeng discovered that the netfiler subsystem in the Linux kernel did
not properly calculate array offsets, leading to a out-of-bounds write
vulnerability. A local user could use this to cause a denial of service
(system crash) or possibly execute arbitrary code. (CVE-2023-42753)
Bing-Jhong Billy Jheng discovered that the Unix domain socket
implementation in the Linux kernel contained a race condition in certain
situations, leading to a use-after-free vulnerability. A local attacker
could use this to cause a denial of service (system crash) or possibly
execute arbitrary code. (CVE-2023-4622)
Budimir Markovic discovered that the qdisc implementation in the Linux
kernel did not properly validate inner classes, leading to a use-after-free
vulnerability. A local user could use this to cause a denial of service
(system crash) or possibly execute arbitrary code. (CVE-2023-4623)
