Summary

Zhenpeng Lin discovered that the network packet scheduler implementation in
the Linux kernel did not properly remove all references to a route filter
before freeing it in some situations. A local attacker could use this to
cause a denial of service (system crash) or execute arbitrary code.
(CVE-2022-2588)

It was discovered that the netfilter subsystem of the Linux kernel did not
prevent one nft object from referencing an nft set in another nft table,
leading to a use-after-free vulnerability. A local attacker could use this
to cause a denial of service (system crash) or execute arbitrary code.
(CVE-2022-2586)

It was discovered that the implementation of POSIX timers in the Linux
kernel did not properly clean up timers in some situations. A local
attacker could use this to cause a denial of service (system crash) or
execute arbitrary code. (CVE-2022-2585)

Minh Yuan discovered that the floppy disk driver in the Linux kernel
contained a race condition, leading to 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-2022-1652)

It was discovered that the Atheros ath9k wireless device driver in the
Linux kernel did not properly handle some error conditions, 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-2022-1679)

Felix Fu discovered that the Sun RPC implementation in the Linux kernel did
not properly handle socket states, leading to a use-after-free
vulnerability. A remote attacker could possibly use this to cause a denial
of service (system crash) or execute arbitrary code. (CVE-2022-28893)

Johannes Wikner and Kaveh Razavi discovered that for some AMD x86-64
processors, the branch predictor could by mis-trained for return
instructions in certain circumstances. A local attacker could possibly use
this to expose sensitive information. (CVE-2022-29900)

Johannes Wikner and Kaveh Razavi discovered that for some Intel x86-64
processors, the Linux kernel's protections against speculative branch
target injection attacks were insufficient in some circumstances. A local
attacker could possibly use this to expose sensitive information.
(CVE-2022-29901)

Arthur Mongodin discovered that the netfilter subsystem in the Linux kernel
did not properly perform data validation. A local attacker could use this
to escalate privileges in certain situations. (CVE-2022-34918)
