CVE-2026-53184
The CVE-2026-53184 issue affects the Linux kernel UDP sockmap path. On UDP receive, skb->dev is repurposed as dev_scratch; when a SK_SKB verdict program uses BPF socket-lookup helpers (bpf_sk_lookup_tcp/udp, bpf_skc_lookup_tcp), skb->dev may still hold the dev_scratch value, and dev_net(skb...

CVE-2026-52946
Summary of CVE-2026-52946 (Linux kernel) Root cause: A SOFTIRQ-unsafe lock order deadlock occurs in fasync signaling for process groups when signals are delivered. Specifically, send_sigio() and send_sigurg() traverse the task list under read_lock(&tasklist_lock) from softirq context, which can d...

Astra Linux – Vulnerability in Linux 6.12
In the Linux kernel, the following vulnerability has been resolved: rcu: Fixed a deadloop in rcureadunlock due to a softirq. The commit 5f5fa7ea89dc “rcu: Do not use negative nesting depth in rcureadunlock” removes the recursion-protection code from rcureadunlock. As a result, the deadloop could ...
PT-2026-51840
Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description A deadlock can occur in the send sigio and send sigurg functions when a process group receives a signal. This happens because these functions use read lock&tasklist lock to traverse the...

CVE-2026-46290
The CVE-2026-46290 issue in Linux kernels’ x86 EFI runtime handling was fixed by replacing in_interrupt() with !in_task() to preserve interrupt/NMI fault handling without being affected by the FPU softirq path. Root cause: kernel_fpu_begin() uses fpregs_lock() with local_bh_disable(), setting SOF...
