CVE-2026-31422

CVE-2026-31422 affects the Linux kernel’s net/sched subsystem. The vulnerability occurs in flow_change() where tcf_block_q() dereferences q->handle to derive a default baseclass for shared blocks, while block->q can be NULL for shared blocks. The fix adds a check of tcf_block_shared() befor...

nodejs: Nodejs denial of service

A flaw in Node.js TLS error handling allows remote attackers to crash or exhaust resources of a TLS server when pskCallback or ALPNCallback are in use. Synchronous exceptions thrown during these callbacks bypass standard TLS error handling paths tlsClientError and error, causing either immediate...
