CVE-2023-53790 bpf: Zeroing allocated object from slab in bpf memory allocator

In the Linux kernel, the following vulnerability has been resolved: bpf: Zeroing allocated object from slab in bpf memory allocator Currently the freed element in bpf memory allocator may be immediately reused, for htab map the reuse will reinitialize special fields in map value e.g., bpfspinlock...

CVE-2022-50650

The CVE-2022-50650 entry concerns the Linux kernel BPF verifier and synchronous callbacks. The issue arises because the verifier treats callbacks as if they execute only once, which mismanages reference state for for_each style helpers that invoke callbacks multiple times. This can lead to refere...

DEBIAN-CVE-2025-40319

In the Linux kernel, the following vulnerability has been resolved: bpf: Sync pending IRQ work before freeing ring buffer Fix a race where irqwork can be queued in bpfringbufcommit but the ring buffer is freed before the work executes. In the syzbot reproducer, a BPF program attached to schedswit...

CVE-2025-40319

The CVE-2025-40319 issue is a race in the Linux kernel’s BPF ring buffer handling. Specifically, a BPF program can queue irq_work via bpf_ringbuf_commit(), and if the ring buffer is freed before the work runs, the irq_work thread may access freed memory. The documented fix is to synchronize pendi...
