SUSE CVE-2026-46137

In the Linux kernel, the following vulnerability has been resolved: mptcp: pm: ADDADDR rtx: fix potential data-race This mptcppmaddtimer helper is executed as a timer callback in softirq context. To avoid any data races, the socket lock needs to be held with bhlocksock. If the socket is in use,...

CVE-2026-46137

A flaw was found in the Linux kernel, specifically within the Multipath TCP MPTCP implementation. The mptcppmaddtimer helper, which is executed as a timer callback, does not properly hold the socket lock when operating in a softirq context. This oversight can lead to a potential data race, which...

CVE-2026-46227 sctp: revalidate list cursor after sctp_sendmsg_to_asoc() in SCTP_SENDALL

In the Linux kernel, the following vulnerability has been resolved: sctp: revalidate list cursor after sctpsendmsgtoasoc in SCTPSENDALL The SCTPSENDALL path in sctpsendmsg iterates ep-asocs with listforeachentrysafe, which caches the next entry in @tmp before the loop body runs. The body calls...

CVE-2026-46227

CVE-2026-46227 describes a race in the Linux kernel SCTP SENDALL path. The sctp_sendmsg() loop over ep->asocs caches the next entry in @tmp, then calls sctp_sendmsg_to_asoc() after dropping the socket lock, allowing a second thread to peel off the cached association and migrate it to a new end...

CVE-2026-46137

CVE-2026-46137 affects the Linux kernel MPTCP implementation. The mptcp_pm_add_timer() helper runs as a timer callback in softirq context and can race with socket state unless the socket lock is held with bh_lock_sock(). The mitigation is to hold the lock and retry if the socket is in use, mirror...

PT-2026-61288

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description A race condition exists between the sctp wait for connect function and the peeloff process. The sctp wait for connect function releases and subsequently re-acquires the socket lock while...

Linux kernel 安全漏洞

The Linux kernel is the core of the open-source operating system Linux, developed by the Linux Foundation in the United States. There is a security vulnerability in the Linux kernel, which stems from the SCTPSENDALL path, where sctpsendmsgtoasoc may release the socket lock, causing other threads ...

CVE-2026-43023

CVE-2026-43023 affects the Linux kernel Bluetooth SCO path. A race condition in sco_sock_connect() allows two concurrent connect() attempts on the same socket to bypass locks, leading to use-after-free and potential socket/state corruption (BT_OPEN -> BT_CONNECT with zombie sk). The issue is d...
