CVE-2026-90107

CVE-2026-90107 is a memory leak in the Linux kernel's SMC (Shared Memory Communications) module, specifically in smc_llc_flow_stop(). A blind memset zeroes the flow struct without first freeing a potentially non-NULL flow->qentry pointer. The leak is triggered when a late-arriving duplicate CO...

CVE-2026-90065 net/smc: release the internal TCP sock on IPPROTO_SMC socket creation failure

In the Linux kernel, the following vulnerability has been resolved: net/smc: release the internal TCP sock on IPPROTOSMC socket creation failure IPPROTOSMC sockets create an internal TCP sock "clcsock" from the proto-init hook. When socket creation fails after proto-init has run - e.g. a cgroup B...

CVE-2026-90063

CVE-2026-90063 is a vulnerability in the Linux kernel's virtio-net driver. A user can specify a gso_size smaller than 8 (below TCP_MIN_GSO_SIZE) in a packet crafted via an AF_PACKET PACKET_VNET_HDR socket. Because GSO_MAX_SIZE equals 8 × 65535, dividing the SKB length by a gso_size

CVE-2026-90058

CVE-2026-90058 is a Linux kernel vulnerability in the net/sched subsystem. The root cause is that qdisc_get_stab() accepts a user-supplied size table, and __qdisc_calculate_pkt_len() amplifies qdisc_pkt_len() through overhead, size-table data (u16), and size_log, allowing a crafted stab to set th...
