Vulnerability from github – Published: 2026-10-18 18:32 – Updated: 2026-10-18 18:32

Details

In the Linux kernel, the following vulnerability has been resolved:

octeontx2-pf: Fix aura BPID assignment when CONFIG_DCB is enabled

Previously, BPID assignment under CONFIG_DCB assumed queue_to_pfc_map was always initialized. For SDP VFs this leads to invalid memory access as it was not initialized.

This patch adds a NULL check for queue_to_pfc_map before dereferencing it. Also, simplifies the logic by always assigning a default BPID first, then conditionally overriding it if CONFIG_DCB is enabled and the map exists.
