CVE-2026-53292

The CVE concerns the Linux kernel phonet code path where pn_socket_autobind() could trigger a kernel BUG_ON() when a failed bind returns -EINVAL but pn_port() remains 0. The root cause is that pn_socket_bind() could return -EINVAL when sk->sk_state is not TCP_CLOSE even if the socket was never...

CVE-2026-53283

CVE-2026-53283 covers a bounds-check failure in the Linux kernel AMD IOMMU path. The issue arises in __rlookup_amd_iommu(): rlookup_table[devid] is indexed without an internal bounds check, and iommu_device_register() iterates all PCI devices, calling amd_iommu_probe_device() for each. If a devic...

CVE-2026-53280

The CVE-2026-53280 issue affects the Linux kernel IOMMU path. A NULL group->domain could be dereferenced in pci_dev_reset_iommu_done() when a default domain fails to allocate during the first probe, potentially causing a crash at domain->ops->attach_dev invoked by __iommu_attach_device()...

CVE-2026-52961

A flaw was found in the Linux kernel's Ceph filesystem component. A race condition exists in the cephbuildxattrsblob function where the required extended attribute xattr blob size is computed before the buildxattrs call. During this window, another process can update the xattr blob, leading to a...

CVE-2026-53059

A flaw was found in the Linux kernel's device-mapper log dm log component. A local attacker could exploit an integer overflow vulnerability where a 64-bit value is truncated to 32 bits, leading to undersized memory allocations. This allows for out-of-bounds writes to kernel memory during log...

CVE-2026-53166

The CVE-2026-53166 entry documents a Linux kernel vulnerability in futex/requeue where a NULL pointer dereference can occur in remove_waiter() during self-deadlock. Root cause: when FUTEX_CMP_REQUEUE_PI requeues a non-top waiter that already owns the target PI futex, task_blocks_on_rt_mutex() ret...

kernel: ip6_tunnel: clear skb2->cb[] in ip4ip6_err()

A flaw was found in the Linux kernel's IPv6 tunnel implementation. A remote attacker could exploit this flaw by sending malicious ICMPv6 error messages to cause a stack-based buffer overflow in the kernel's IPv4-over-IPv6 tunnel error handling code. This could result in a kernel crash denial of...
