Pratyush Yadav discovered that the Xen network backend implementation in
the Linux kernel did not properly handle zero length data request, leading
to a null pointer dereference vulnerability. An attacker in a guest VM
could possibly use this to cause a denial of service (host domain crash).
(CVE-2023-46838)
It was discovered that the Habana’s AI Processors driver in the Linux
kernel did not properly initialize certain data structures before passing
them to user space. A local attacker could use this to expose sensitive
information (kernel memory). (CVE-2023-50431)
It was discovered that the device mapper driver in the Linux kernel did not
properly validate target size during certain memory allocations. A local
attacker could use this to cause a denial of service (system crash).
(CVE-2023-52429, CVE-2024-23851)
It was discovered that the CIFS network file system implementation in the
Linux kernel did not properly validate certain SMB messages, leading to an
out-of-bounds read vulnerability. An attacker could use this to cause a
denial of service (system crash) or possibly expose sensitive information.
(CVE-2023-6610)
Yang Chaoming discovered that the KSMBD implementation in the Linux kernel
did not properly validate request buffer sizes, leading to an out-of-bounds
read vulnerability. An attacker could use this to cause a denial of service
(system crash) or possibly expose sensitive information. (CVE-2024-22705)
Chenyuan Yang discovered that the btrfs file system in the Linux kernel did
not properly handle read operations on newly created subvolumes in certain
conditions. A local attacker could use this to cause a denial of service
(system crash). (CVE-2024-23850)
Several security issues were discovered in the Linux kernel.
An attacker could possibly use these to compromise the system.
This update corrects flaws in the following subsystems:
– Android drivers;
– Userspace I/O drivers;
– F2FS file system;
– SMB network file system;
– Networking core;
(CVE-2023-52434, CVE-2023-52436, CVE-2023-52435, CVE-2023-52439,
CVE-2023-52438)
