In the Linux kernel, the following vulnerability has been resolved: eth: bnxt: return fail if interface is down in bnxt_queue_mem_alloc() The bnxt_queue_mem_alloc() is called to allocate new queue memory when a queue is restarted. It internally accesses rx buffer descriptor corresponding to the index. The rx buffer descriptor is allocated and set when the interface is up and it's freed when the interface is down. So, if queue is restarted if interface is down, kernel panic occurs. Splat looks like: BUG: unable to handle page fault for address: 000000000000b240 #PF: supervisor read access in kernel mode #PF: error_code(0x0000) - not-present page PGD 0 P4D 0 Oops: Oops: 0000 [#1] PREEMPT SMP NOPTI CPU: 3 UID: 0 PID: 1563 Comm: ncdevmem2 Not tainted 6.14.0-rc2+ #9 844ddba6e7c459cafd0bf4db9a3198e Hardware name: ASUS System Product Name/PRIME Z690-P D4, BIOS 0603 11/01/2021 RIP: 0010:bnxt_queue_mem_alloc+0x3f/0x4e0 [bnxt_en] Code: 41 54 4d 89 c4 4d 69 c0 c0 05 00 00 55 48 89 ...
