kernel: bpf, sockmap: Prevent lock inversion deadlock in map delete elem

CVE-2024-35895 addresses a vulnerability in the Linux kernel's Berkeley Packet Filter BPF subsystem, specifically within the sockmap feature. The issue arises when BPF tracing programs, which can execute in various interrupt contexts, attempt to delete elements from sockmap or sockhash maps. This...

The vulnerability of the bpf component in the Linux operating system’s kernel allows a hacker to trigger a service failure.

The vulnerability of the bpf component in the Linux operating system’s kernel is related to a failure in bpfspinlock, when it is set as the value of bpftimer. This occurs because the bpfmapupdateelem call reassigns another timer object. Exploiting this vulnerability can allow an attacker to trigg...
