Description

CVE-2024-36927 is a vulnerability in the Linux kernel's IPv4 implementation where uninitialized memory is accessed in the __ip_make_skb() function. This occurs due to a race condition involving the IP_HDRINCL socket option, leading to potential use of uninitialized icmphdr data. The flaw was detected by Kernel Memory Sanitizer (KMSAN) and fixed by changing the way flags are checked and explicitly initializing certain fields in raw_sendmsg().
