In the Linux kernel, the following vulnerability has been resolved: misc: nsm: bound the device-reported response length nsmsendrecvmsglocked stores the virtqueue used-ring length reported by the NSM device into msg-resp.len without bounding it to the response buffer. A malicious or buggy backend...

CVE-2026-89741

CVE-2026-89741 affects the Linux kernel V4L2 subsystem, specifically the __video_register_device() function. A prior patch (commit 2a934fdb01db) attempted to improve error handling by calling put_device() when device_register() fails, but this conflicts with the V4L2 API contract requiring caller...

CVE-2026-89735 usb: gadget: midi2: remove default configfs groups on teardown

CVE-2026-89735

CVE-2026-89735 is a memory leak in the Linux kernel 's USB gadget MIDI 2.0 driver. During function teardown in f_midi2_free_inst() or endpoint cleanup in f_midi2_ep_opts_release(), the function configfs_remove_default_groups() was never called, so the internal refcounts of the default configfs ch...

CVE-2026-89715

CVE-2026-89715 is a reference leak in the Linux kernel NFS/localio subsystem. When nfs_uuid_add_file() races with nfs_uuid_put() tearing down uuid->net, it returns -ENXIO without publishing the RCU pointer. The error path in nfs_open_local_fh() then leaks a caller-owned nfsd_file reference (pi...

CVE-2026-89714 NFS: fix delegation_hash_table leak when nfs4_server_common_setup() fails

In the Linux kernel, the following vulnerability has been resolved: NFS: fix delegationhashtable leak when nfs4servercommonsetup fails nfs4servercommonsetup allocates server-delegationhashtable first, but server-destroy - the only path that frees the table via nfs4destroyserver - is not assigned...

CVE-2026-89714

This Linux kernel vulnerability affects the NFSv4 client subsystem. The root cause is a memory leak of server->delegation_hash_table (4 KiB per attempt with the default delegation watermark) when nfs4_server_common_setup() fails at an intermediate step (is_ds_only_client(), nfs4_init_session()...

CVE-2026-89710

CVE-2026-89710 is a layout segment leak in the Linux kernel's NFSv4.1/pNFS subsystem. When the server returns a new layout stateid while a valid one is still held, pnfs_layout_process() jumps to out_forget without draining the on-stack free_me list; only the success path calls pnfs_free_lseg_list...

CVE-2026-89707

CVE-2026-89707 affects the Linux kernel nfsd subsystem, specifically the nfsd_cross_mnt() function. The root cause is a missing path_put() call in the error path when follow_down() returns a negative value, leaving the mntget()/dget() references acquired on entry unreleased. The impact is a memor...
