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...
