CVE-2026-72502

The CVE-2026-72502 issue affects the Linux kernel TCP/IPv6 path: when MTU is large, ip6_default_advmss() could return IPV6_MAXPLEN (65535), which TCP could treat as mss_clamp, allowing an MSS of 65535. The bug also coalesces with GSO_BY_FRAGS (0xFFFF), causing a NULL pointer dereference if a TCP ...

EUVD-2026-59401

In the Linux kernel, the following vulnerability has been resolved: tcp: ipv6: clamp default adverting MSS to avoid GSOBYFRAGS 0xFFFF When MTU is large, ip6defaultadvmss can return IPV6MAXPLEN 65535. This is interpreted by TCP as mssclamp, allowing the MSS to reach 65535. However, 0xFFFF is also...
