UBUNTU-CVE-2026-74611

In the Linux kernel, the following vulnerability has been resolved: tls: rx: restore msgiter before TLS 1.3 optimistic retry tlsdecryptsg advances msg-msgiter when it maps user pages for the optimistic TLS 1.3 zero-copy path. If the decrypted record turns out not to be unpadded application data,...

CVE-2026-74707

CVE-2026-74707 affects the Linux kernel's xsk (AF_XDP sockets) component, specifically the zero-copy TX path . The root cause is a time-of-check-to-time-of-use (TOCTOU) flaw: TX metadata is validated when obtaining the descriptor context but then read again later when preparing the hardware reque...

CVE-2026-74611

CVE-2026-74611 affects the Linux kernel TLS 1.3 receive path. When optimistic zero-copy is enabled via TLS_RX_EXPECT_NO_PAD, tls_decrypt_sg() advances msg->msg_iter to map user pages. If the decrypted record is not unpadded application data (e.g., a TLS 1.3 control record), tls_decrypt_sw() re...

PT-2026-79712

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description An issue exists in the zero-copy path where TX metadata is validated during the acquisition of the descriptor context but read again when preparing the hardware request. This allows user...
