CVE-2026-18417

The Zephyr RTOS native BSD-socket layer contains a wild pointer dereference vulnerability when a TCP listening socket reports an asynchronous error. The root cause is type-punning an error status into the user_data field of struct net_context. In version v4.3.0 , a second interface-down event can...

Time-of-check Time-of-use (TOCTOU) Race Condition

Apache Tomcat is vulnerable to Time-of-check Time-of-use TOCTOU Race Condition. The vulnerability is due to a race condition during the creation of Unix domain sockets, which allows an unauthorized local attacker to exploit the timing window and gain access to the Unix domain socket...

CVE-2026-97984 net: ipv6: Fix UDP length overflow with PMTU discover and big MTU

In the Linux kernel, the following vulnerability has been resolved: net: ipv6: Fix UDP length overflow with PMTU discover and big MTU This commit bounds cork-base.fragsize to IP6MAXMTU for UDP sockets to avoid a possible overflow of UDP length that triggers a WARN in udpsetlenshort when setsockop...

CVE-2026-94624

A flaw was found in vLLM. A remote attacker can exploit a denial of service vulnerability in the P2P KV offloading mechanism. By supplying arbitrary remote host and port values, an attacker can create unreachable peer sessions that consume ZeroMQ sockets. This resource exhaustion leads to an...

USN-8801-1: Linux kernel (Azure CVM) vulnerabilities

It was discovered that some Arm processors could complete a broadcast translation lookaside buffer TLB invalidation before memory writes made through the invalidated translation were globally observed. A local attacker could possibly use this to write to memory after permission to do so had been...

Ubuntu 24.04 LTS / 26.04 LTS : Linux kernel (Azure CVM) vulnerabilities (USN-8801-1)

The remote Ubuntu 24.04 LTS / 26.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-8801-1 advisory. It was discovered that some Arm processors could complete a broadcast translation lookaside buffer TLB invalidation before memory writes made...

CVE-2026-90430

In the Linux kernel, the following vulnerability has been resolved: iommu/tegra241-cmdqv: Publish an LVCMDQ only after it is fully initialized tegra241vintfinitlvcmdq stores the freshly allocated vcmdq pointer to the vintf-lvcmdqs array, before tegra241vcmdqallocsmmucmdq builds the vcmdq-cmdq. Th...

CVE-2026-15924 Use-after-free / double-free from unsynchronized concurrent access to the TLS client session cache in Zephyr sockets

Zephyr's TLS socket layer in subsys/net/lib/sockets/socketstls.c keeps a single process-global array, clientcache, of cached client sessions that is shared by every TLS socket context. The functions that mutate and read it — tlssessionsave, tlssessionget, tlssessioncachereset, and the settings...
