kernel: net/ipv6: ioam6: prevent schema length wraparound in trace fill

A flaw was found in the Linux kernel's IPv6 In-situ Operations, Administration, and Maintenance IOAM6 trace fill functionality. An integer overflow vulnerability exists in the ioam6filltracedata function, where the schema length calculation can wrap around due to being stored in an 8-bit unsigned...

kernel: mptcp: fix slab-use-after-free in __inet_lookup_established

A flaw was found in the Linux kernel's Multipath TCP MPTCP implementation. Due to incorrect memory allocation for IPv6 subflow child sockets, a use-after-free vulnerability exists. A remote attacker could exploit this by triggering concurrent lookups in the kernel's hash table, potentially leadin...

EUVD-2026-41541

Net::IP::LPM versions through 1.10 for Perl allow a heap out-of-bounds read via an unbounded prefix length. add passes the prefix string to the trie builder addPrefixToTrie without checking it against the address width. addPrefixToTrie then walks the prefix buffer by prefixlength bits, reading...

CVE-2026-56015

The Net::IP::LPM Perl module (versions prior to 1.11 ) is vulnerable to a heap out-of-bounds read caused by an unbounded prefix length. The add() function fails to verify if a prefix length exceeds the address width (32 bits for IPv4, 128 bits for IPv6) before passing it to addPrefixToTrie(). Thi...
