USN-5567-1: Linux kernel (OEM) vulnerabilities<\/p>\n
Zhenpeng Lin discovered that the network packet scheduler implementation in
\nthe Linux kernel did not properly remove all references to a route filter
\nbefore freeing it in some situations. A local attacker could use this to
\ncause a denial of service (system crash) or execute arbitrary code.
\n(CVE-2022-2588)<\/p>\n
It was discovered that the netfilter subsystem of the Linux kernel did not
\nprevent one nft object from referencing an nft set in another nft table,
\nleading to a use-after-free vulnerability. A local attacker could use this
\nto cause a denial of service (system crash) or execute arbitrary code.
