https://notcve.org/view.php?id=CVE-2024-49938
21 Oct 2024 — In the Linux kernel, the following vulnerability has been resolved: wifi: ath9k_htc: Use __skb_set_length() for resetting urb before resubmit Syzbot points out that skb_trim() has a sanity check on the existing length of the skb, which can be uninitialised in some error paths. The intent here is clearly just to reset the length to zero before resubmitting, so switch to calling __skb_set_length(skb, 0) directly. In addition, __skb_set_length() already contains a call to skb_reset_tail_pointer(), so remove th... • https://git.kernel.org/stable/c/e6b9bf32e0695e4f374674002de0527d2a6768eb • CWE-824: Access of Uninitialized Pointer •
