kernel: netfilter: nf_tables: release flowtable after rcu grace period on error

A flaw was found in the Linux kernel's netfilter component, specifically within the nftables subsystem. An error in releasing a flowtable after an RCU Read-Copy-Update grace period could lead to a use-after-free vulnerability. This issue could expose the flowtable to the packet path and...

USN-8441-1 linux-aws-hwe, linux-azure, linux-gcp, linux-hwe, linux-oracle vulnerabilities

It was discovered that the Linux kernel algifaead module did not properly handle in-place cryptographic operations. This flaw is known as Copy Fail. A local attacker could use this to escalate privileges, or possibly escape a container. CVE-2026-31431 Several security issues were discovered in th...
