Summary
It was discovered that a race condition existed in the instruction emulator
of the Linux kernel on Arm 64-bit systems. A local attacker could use this
to cause a denial of service (system crash). (CVE-2022-20422)
Hsin-Wei Hung discovered that the BPF subsystem in the Linux kernel
contained an out-of-bounds read vulnerability in the x86 JIT compiler. A
local attacker could possibly use this to cause a denial of service (system
crash) or expose sensitive information (kernel memory). (CVE-2022-2905)
Hao Sun and Jiacheng Xu discovered that the NILFS file system
implementation in the Linux kernel contained 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-2022-2978)
Abhishek Shah discovered a race condition in the PF_KEYv2 implementation in
the Linux kernel. A local attacker could use this to cause a denial of
service (system crash) or possibly expose sensitive information (kernel
memory). (CVE-2022-3028)
It was discovered that the Netlink device interface implementation in the
Linux kernel did not properly handle certain error conditions, leading to a
use-after-free vulnerability with some network device drivers. A local
attacker with admin access to the network device could use this to cause a
denial of service (system crash) or possibly execute arbitrary code.
(CVE-2022-3625)
It was discovered that the IDT 77252 ATM PCI device driver in the Linux
kernel did not properly remove any pending timers during device exit,
resulting in a use-after-free vulnerability. A local attacker could
possibly use this to cause a denial of service (system crash) or execute
arbitrary code. (CVE-2022-3635)
Gwangun Jung discovered that the netfilter subsystem in the Linux kernel
did not properly prevent binding to an already bound chain. A local
attacker could use this to cause a denial of service (system crash).
(CVE-2022-39190)
Xingyuan Mo and Gengjia Chen discovered that the Promise SuperTrak EX
storage controller driver in the Linux kernel did not properly handle
certain structures. A local attacker could potentially use this to expose
sensitive information (kernel memory). (CVE-2022-40768)
