USN-5567-1: Linux kernel (OEM) vulnerabilities
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)
