In the Linux kernel, the following vulnerability has been resolved: netfilter: validate user input for expected length I got multiple syzbot reports showing old bugs exposed by BPF after commit 20f2505fb436 "bpf: Try to avoid kzalloc in cgroup/s,getsockopt" setsockopt @optlen argument should be...

CVE-2024-35895 bpf, sockmap: Prevent lock inversion deadlock in map delete elem

In the Linux kernel, the following vulnerability has been resolved: bpf, sockmap: Prevent lock inversion deadlock in map delete elem syzkaller started using corpuses where a BPF tracing program deletes elements from a sockmap/sockhash map. Because BPF tracing programs can be invoked from any...

CVE-2024-35895

The CVE-2024-35895 vulnerability affects the Linux kernel, specifically the BPF sockmap/sockhash path. A deadlock could occur when map_delete_elem is invoked from a context where interrupts are disabled; the fix adds a hardirq-safety check to bail out if map_delete_elem runs in a non-hardirq-unsa...

CVE-2024-35894

CVE-2024-35894: In the Linux kernel, a mitigation for a subflow-level BPF access issue was implemented in mptcp by preventing BPF from accessing mptcp-level proto_ops from a subflow scope. The root cause was a misconfigured interaction where BPF could reach mptcp proto_ops through a tcp subflow, ...
