CVE-2024-26851

CVE-2024-26851 concerns the Linux kernel netfilter nf_conntrack_h323 path. The issue arises when decoding H.323 ras messages: an abnormal skb->data can cause the extension bitmap length to exceed 32, leading to a length-based shift that may become negative and trigger UBSAN reports. The workar...
