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-2026-89730

CVE-2026-89730 affects the Linux kernel 's altera-cvp FPGA driver. In the function altera_cvp_send_block() , the trailing-byte code path dereferences a u32 pointer even when only 1–3 bytes remain in the input buffer. When the buffer ends at a page or scatterlist boundary, this causes an out-of-bo...

CVE-2026-89723

CVE-2026-89723 is a slab-out-of-bounds vulnerability in the Linux kernel's nilfs2 filesystem. After truncating a file, an intermediate B-tree node block is left in the node cache in a dirty state instead of being deleted. The log writer then incorrectly invokes nilfs_direct_propagate() on that no...

CVE-2026-89706

In the Linux kernel NFS server (nfsd) , the write verifier (nn->writeverf) is not rotated when an async COPY operation's post-copy writeback fails. As a result, a client that receives NFS_UNSTABLE via CB_OFFLOAD and subsequently issues COMMIT receives the same verifier value , leading the clie...

CVE-2026-89705

CVE-2026-89705 is a lockless reader out-of-bounds read in the Linux kernel's nfsd component. The nfsd_dispatch() function uses rq_status_counter as a seq-lock protocol: it sets the counter to an odd value after decoding a request and back to even after full processing. However, the cache-hit (RC_...
