CVE-2026-98950

A flaw was found in the Linux kernel. A remote attacker could trigger a Denial of Service DoS or improper packet routing due to an integer truncation vulnerability within the Berkeley Packet Filter BPF flow dissector. When handling packets with header lengths exceeding 16-bit limits 65,535 bytes,...

kernel: tcp: restrict SO_ATTACH_FILTER to priv users

A flaw was found in the Linux kernel's handling of TCP sockets. An unprivileged application can exploit this vulnerability by attaching a Berkeley Packet Filter BPF using the SOATTACHFILTER option. This allows the application to conduct a side-channel attack, leading to the leakage of sensitive T...

CVE-2026-98631

A flaw was found in the Linux kernel. A local attacker can cause a Denial of Service DoS or potentially expose sensitive memory by triggering an out-of-bounds read in the Berkeley Packet Filter BPF socket map implementation. This issue occurs because socket map lookups perform a 64-bit comparison...

CVE-2026-98642

A flaw was found in the Linux kernel's Berkeley Packet Filter BPF memory allocator. A race condition occurs when bulk memory allocation and memory cleanup run concurrently without adequate synchronization. A local attacker could exploit this flaw to trigger a use-after-free condition, leading to ...

CVE-2026-98590

A flaw was found in the Linux kernel's Berkeley Packet Filter BPF subsystem. An error in context code generation incorrectly sign-extends register values when reading socket queue mappings, causing runtime register values to exceed boundaries tracked by the kernel's safety verifier. A local user...
