CVE-2026-74740
CVE-2026-74740 is a TOCTOU (time-of-check-time-of-use) NULL pointer dereference in the Linux kernel's net/sched: act_api subsystem. When handling TC_ACT_GOTO_CHAIN, tcf_action_exec() performs an initial rcu_access_pointer(a->goto_chain) check, then calls tcf_action_goto_chain_exec() which perf...
CVE-2026-74740 net/sched: act_api: fix TOCTOU NULL deref on a->goto_chain
In the Linux kernel, the following vulnerability has been resolved: net/sched: actapi: fix TOCTOU NULL deref on a-gotochain tcfactionexec handles TCACTGOTOCHAIN by first checking rcuaccesspointera-gotochain and then calling tcfactiongotochainexec, which does a second, independent...
CVE-2026-74739
CVE-2026-74739 is a slab-out-of-bounds read in the Linux kernel's net/sched cls_u32 traffic classification module. The root cause is in u32_bind_class(), which unconditionally casts a handle to tc_u_knode and dereferences &n->res; when the handle is actually a tc_u_hnode (hash table node with ...
net/http: golang: Go net/http: Unencrypted HTTP/2 connections vulnerable to Denial of Service
A flaw was found in the net/http component of the Go standard library. When a server is configured to support unencrypted HTTP/2, it reads initial bytes from new connections to detect the HTTP/2 client preface. However, the ReadHeaderTimeout is not correctly applied during this process. This...
net/url: golang: golang net/url: Denial of Service from quadratic complexity in path resolution
A flaw was found in net/url, a component of golang. This vulnerability arises when resolving relative paths that contain numerous parent directory '..' segments. A remote attacker could exploit this by providing a specially crafted path, leading to quadratic time complexity and excessive memory...

golang.org/x/net/idna: golang: net/http: golang.org/x/net/idna: Privilege escalation via incorrect Punycode label processing
A flaw was found in golang.org/x/net/idna. ToASCII and ToUnicode incorrectly accept Punycode-encoded labels that decode to an ASCII-only hostname for example, xn--example-.com returns example.com instead of an error. Applications that validate the ASCII form then convert to Unicode may grant acce...
