Description

CVE-2024-50145 affecting package kernel for versions less than 6.6.64.2-1

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

octeon_ep: Add SKB allocation failures handling in __octep_oq_process_rx()

build_skb() returns NULL in case of a memory allocation failure so handle

it inside __octep_oq_process_rx() to avoid NULL pointer dereference.

__octep_oq_process_rx() is called during NAPI polling by the driver. If

skb allocation fails, keep on pulling packets out of the Rx DMA queue: we

shouldn't break the polling immediately and thus falsely indicate to the

octep_napi_poll() that the Rx pressure is going down. As there is no

associated skb in this case, don't process the packets and don't push them

up the network stack - they are skipped.

Helper function is implemented to unmmap/flush all the fragment buffers

used by the dropped packet. 'alloc_failures' counter is incremented to

mark the skb allocation error in driver statistics.

Found by Linux Verification Center (linuxtesting.org) with SVACE.

How this vulnerability can be exploited

This issue can be reached with local access to the system, attack complexity is low, an attacker needs low-level privileges on the target. No user interaction is required. The scope is unchanged, so the impact stays within the vulnerable component. Rated impact: confidentiality none, integrity none, availability high.
