CVE-2026-45952

A flaw was found in the Linux kernel's fbnic driver. This vulnerability allows a local user to cause a Denial of Service DoS by increasing the Maximum Transmission Unit MTU beyond the hardware's threshold while an eXpress Data Path XDP program is attached. This improper validation of MTU changes...

UBUNTU-CVE-2026-46015

In the Linux kernel, the following vulnerability has been resolved: tcp: call skdataready after listener migration When inetcsklistenstop migrates an established child socket from a closing listener to another socket in the same SOREUSEPORT group, the target listener gets a new accept-queue entry...

CVE-2026-46015

The CVE-2026-46015 issue affects the Linux kernel TCP path when migrating an established child socket between listeners in the same SO_REUSEPORT group. After inet_csk_listen_stop() migrates, the target listener can obtain a new accept-queue entry via inet_csk_reqsk_queue_add(), but the path does ...

CVE-2026-45918

CVE-2026-45918 concerns a race condition in the Linux kernel related to OpenVPN TCP handling. When a peer is kept alive and later removed, the kernel temporarily places the peer in a release list and detaches from the socket by restoring its proto and socket callbacks. If userspace closes the soc...

CVE-2026-45889

Summary: CVE-2026-45889 affects the Linux kernel’s Multipath TCP (MPTCP). The root cause is incorrect accounting for Out-of-Order (OoO) data in mptcp_rcvbuf_grow(), causing the MPTCP receive buffer to drift toward tcp_rmem[2]. The vulnerability is linked to a subtle race during rcvspace initializ...

CVE-2026-45843

CVE-2026-45843 affects the Linux kernel’s SLIP/VJ-compressed TCP header handling (slip and slhc_uncompress). The vulnerability stems from decode() and pull16() not enforcing bounds against the packet end, and decode() masking its return value to 0xFFFF, causing potential over-reads when a compres...
