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...
