Ubuntu Security Notice USN-5566-1
Posted Aug 11, 2022
Authored by Ubuntu | Site security.ubuntu.com

Ubuntu Security Notice 5566-1 - 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 or execute arbitrary code. 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 or execute arbitrary code.
