CVE-2026-52935

A flaw was found in the Linux kernel. The espintcp component, responsible for handling encrypted network traffic, incorrectly reuses a partial data transmission state. This can lead to an out-of-bounds read, which may allow an attacker to access sensitive information or cause other memory...

CVE-2026-52935 xfrm: espintcp: do not reuse an in-progress partial send

In the Linux kernel, the following vulnerability has been resolved: xfrm: espintcp: do not reuse an in-progress partial send espintcp keeps a single in-flight transmit in ctx-partial. Before building a new skmsg, espintcpsendmsg first tries to flush that state through espintcppushmsgs. For blocki...

CVE-2026-52935

In the Linux kernel, CVE-2026-52935 affects the espintcp path under xfrm, where a retransmit/reuse of an in-flight partial send could lead to an out-of-bounds read in the send path. The root cause is reinitializing an sk_msg and reusing ctx->partial while a previous transfer still owns that st...

CVE-2026-31518

A flaw was found in the Linux kernel. When the espintcp component processes network traffic using asynchronous cryptography, a memory leak can occur. This happens because a socket buffer skb is not correctly released if the transmit queue becomes full. This continuous leak of memory can lead to...
