CVE-2022-49417

CVE-2022-49417 involves the Linux kernel component iwlwifi/mei. The issue is a potential NULL-ptr dereference that could occur when SKB allocation fails; the fix was to skip using the NULL pointer instead of dereferencing it. This vulnerability is described as resolved in multiple sources and is ...

CVE-2024-56639

CVE-2024-56639 affects the Linux kernel net/hsr RedBox path. The root cause was an under-allocated skb in hsr_init_skb() for RedBox, causing skb_over_panic when sending supervision frames that add two TLV components. The issue led to OOPs in skb_panic at net/core/skbuff.c:206 and a local exploit ...
