CVE-2026-74386 nvmet-tcp: fix page fragment cache leak in error path

In the Linux kernel, the following vulnerability has been resolved: nvmet-tcp: fix page fragment cache leak in error path In nvmettcpallocqueue, when a connection is closed during the allocation process e.g., nvmettcpsetqueuesock returns -ENOTCONN, the error handling jumps to outdestroysq and the...

CVE-2026-74385

CVE-2026-74385 affects the Linux kernel’s nvmet-tcp component. The vulnerability arises because nvmet_tcp_set_queue_sock() return value is ignored in nvmet_tcp_tls_handshake_done(), so if the call fails (e.g., socket not TCP_ESTABLISHED), socket callbacks aren’t set and queues/sockets can leak. T...

CVE-2026-74268 tcp: clear sock_ops cb flags before force-closing a child socket

In the Linux kernel, the following vulnerability has been resolved: tcp: clear sockops cb flags before force-closing a child socket A child socket inherits the listener's bpfsockopscbflags via skclonelock. If its setup fails in tcpv4synrecvsock / tcpv6synrecvsock, the child is freed through...

CVE-2026-74268

This CVE describes a Linux kernel vulnerability where a child socket can inherit BPF sock_ops cb flags from the listener through sk_clone_lock(), leading to a crash or compromised handling if its setup fails in tcp_v4_syn_recv_sock() or tcp_v6_syn_recv_sock(). The root cause is that, on forced-cl...

CVE-2026-72502 tcp: ipv6: clamp default adverting MSS to avoid GSO_BY_FRAGS (0xFFFF)

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...

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 ...
