CVE-2026-35535

CVE-2026-35535 affects Sudo up to 1.9.17p2, before the patch identified as 3e474c2. A failure in a setuid/setgid/setgroups call during privilege drop prior to invoking the mailer is not fatal and can lead to local privilege escalation. The vulnerability is restricted to local attackers with exist...

kernel: nf_tables: use-after-free vulnerability in the nft_verdict_init() function

A flaw was found in the Netfilter subsystem in the Linux kernel. This issue occurs in the nftverdictinit function, allowing positive values as a drop error within the hook verdict, therefore, the nfhookslow function can cause a double-free vulnerability when NFDROP is issued with a drop error tha...
