CVE-2024-35839 is a flaw in the Linux kernel's Netfilter bridge functionality. It occurs when bridging certain packets, such as those involving destination NAT between virtual Ethernet interfaces. A mismatch between the network device associated with a packet and the neighbor's device can lead to incorrect handling, including references to freed memory. This issue could cause system crashes. The problem has been fixed by using safer methods to retrieve the network device during packet processing. Users should update their kernels to a patched version to avoid this vulnerability.

Created kernel tracking bugs for this issue: Affects: fedora-all [bug 2281285] The result of automatic check (that is developed by Alexander Larkin) for this CVE-2024-35839 is: CHECK Maybe valid. Check manually. with impact MODERATE (that is approximation based on flags DANGER NETFILTER SKB ; these flags parsed automatically based on patche data). Such automatic check happens only for Low/Moderates (and only when not from reporter, but parsing already existing CVE). Highs always checked manually (I check it myself and then we check it again in Remediation team). In rare cases some of the Moderates could be increased to High later.
