CVE-2026-18417 Wild pointer dereference in Zephyr BSD sockets when a TCP listening socket reports an asynchronous error

The native BSD-socket layer recorded a pending asynchronous socket error by type-punning it into struct netcontext's void userdata field ctx-userdata = INTTOPOINTER-status in zsockacceptedcb, zsockreceivedcb, zsockconnectedcb and zsockclosectx in subsys/net/lib/sockets/socketsinet.c, reading it...

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.

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...

Astra Linux – Vulnerability in Linux 5.10, Linux

There is a use-after-free vulnerability in the Linux Kernel that can be exploited to achieve local privilege escalation. To exploit this vulnerability, the CONFIGTLS or CONFIGXFRMESPINTCP kernel configuration flags must be set; however, the operation does not require any special privileges. There...

Astra Linux – Vulnerabilities in Linux, Linux-5.10, Linux-5.15

A vulnerability was discovered in the HCI socket implementation due to a missing capability check in the net/bluetooth/hcisock.c file within the Linux kernel. This flaw allows an attacker to execute management commands without authorization, compromising the confidentiality, integrity, and...

Astra Linux – Vulnerability in libvirt

A flaw was discovered in libvirt. The virStoragePoolObjListSearch function does not return a locked pool as expected, leading to a race condition and a denial of service when attempting to lock the same object from another thread. This issue could cause clients connecting to the read-only socket ...

Astra Linux – Vulnerability in Linux, Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: inetdiag: fixed a kernel-infoleak issue for UDP sockets KMSAN reported a kernel-infoleak issue 1 that could be exploited by unprivileged users. After analysis, it turned out that UDP was not initializing r-idiagexpires. Other...

Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: can: j1939: prevents deadlock by changing j1939sockslock to rwlock. The following 3 locks may race against each other, causing a deadlock situation in the Syzbot bug report: - j1939sockslock - activesessionlistlock -...
