CVE-2024-56694

CVE-2024-56694 is a Linux kernel vulnerability where a recursive lock in the stream_verdict/VERDICT path can deadlock when a verdict returns SK_PASS, placing the skb back on its own receive queue and triggering a deadlock in the sk_callback_lock path. The root cause is in the bpf: fix recursive l...

CVE-2025-21642

CVE-2025-21642 affects the Linux kernel’s MPTCP subsystem. The issue arises from using current->nsproxy/netns when accessing per-netns data via sysctl entries (net/mptcp/ctrl.c), which can diverge from the netns the table is associated with. The described consequence is a general protection fa...

CVE-2024-36484

CVE-2024-36484 is a Linux kernel vulnerability where the socket acceptance check was relaxed at accept time (net/ipv4/af_inet.c). The issue can arise when a process shuts down a listener before it enters accept, causing the child to reach accept() in FIN_WAIT1 status after the commit “tcp: defer ...

CVE-2024-42111

CVE-2024-42111 affects the Linux kernel BTRFS qgroup handling. The root cause was a patch (b5357cb268c4) that skipped the qgroup inherit checks when qgroup is disabled, allowing a malformed btrfs_qgroup_inherit structure to pass. This could lead to a slab-out-of-bounds read (KASAN) during transac...

CVE-2026-46031

The CVE-2026-46031 entry describes a Linux kernel issue in the ks8851 network driver where a race/deadlock can occur between TX softirq handling and RX processing when BHs are enabled around IRQ handling. The root cause is a potential deadlock: ks8851_irq() holds a spinlock while ks8851_start_xmi...

CVE-2026-23254

CVE-2026-23254 (Linux kernel): The issue affects UDP GRO in the net/ gro path, where the complete stage incorrectly uses the inner network offset when the encapsulation flag is not reliably zeroed by hardware offloads. The root cause is an assumption that all RX-inserted packets have encapsulatio...
