21 Aug 2024 — In the Linux kernel, the following vulnerability has been resolved: vhost/vsock: always initialize seqpacket_allow There are two issues around seqpacket_allow: 1. seqpacket_allow is not initialized when socket is created. Thus if features are never set, it will be read uninitialized. 2. if VIRTIO_VSOCK_F_SEQPACKET is set and then cleared, then seqpacket_allow will not be cleared appropriately (existing apps I know about don't usually do this but it's legal and there's no way to be sure no one relies on this... • https://git.kernel.org/stable/c/ced7b713711fdd8f99d8d04dc53451441d194c60 •

This may cause the CPU core staying in interrupt context too long and lead to soft lockup under heavy load.

21 Aug 2024 — In the Linux kernel, the following vulnerability has been resolved: perf: Fix event leak upon exit When a task is scheduled out, pending sigtrap deliveries are deferred to the target task upon resume to userspace via task_work. However failures while adding an event's callback to the task_work engine are ignored. And since the last call for events exit happen after task work is eventually closed, there is a small window during which pending sigtrap can be queued though ignored, leaking the event refcount ad... • https://git.kernel.org/stable/c/8bffa95ac19ff27c8261904f89d36c7fcf215d59 • CWE-404: Improper Resource Shutdown or Release •
