CVE-2026-90065

A flaw was found in the Linux kernel's net/smc component. A local unprivileged user can exploit this vulnerability by repeatedly attempting to create IPPROTOSMC sockets while a BPF Berkeley Packet Filter program denies the creation. This leads to a memory leak, allowing the user to consume...

CVE-2026-90108

A flaw was found in the Linux kernel's net/smc component. During a specific state transition in the smcllceventhandler, a previously stashed memory object qentry is overwritten without being properly freed. This oversight leads to a memory leak, where allocated memory is not released, potentially...

CVE-2026-90107

A flaw was found in the Linux kernel's net/smc component. The smcllcflowstop function, responsible for stopping a flow, performs a blind memory reset without first freeing a pending queue entry. This can lead to a memory leak if a duplicate link message arrives during a specific timing window,...
