CVE-2026-89745

This Linux kernel vulnerability affects the debugfs subsystem. A prior commit changed relayfs from using the mmap file operation to mmap_prepare, but the corresponding lockdown check in debugfs was not updated. As a result, when the kernel is in integrity mode , debugfs fails to lock down files t...

CVE-2026-89743

A vulnerability in the Linux kernel's NSM (Network Shared Memory) driver allows a malicious or buggy backend to report a response length larger than the allocated buffer. The function nsm_sendrecv_msg_locked() stores the virtqueue used-ring length without bounding it, so parse_resp_raw() copies e...

CVE-2026-89742

CVE-2026-89742 is a use-after-free vulnerability in the Linux kernel's RapidIO mport character device driver , specifically in the dma_req_free() function. After kref_put() drops the last reference to a mapping and the mapping is freed by mport_release_mapping(), a subsequent mutex_unlock() deref...
