CVE-2024-35903 x86/bpf: Fix IP after emitting call depth accounting

In the Linux kernel, the following vulnerability has been resolved: x86/bpf: Fix IP after emitting call depth accounting Adjust the IP passed to emitpatch so it calculates the correct offset for the CALL instruction if x86calldepthemitaccounting emits code. Otherwise we will skip some instruction...

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, ...
