CVE-2026-64382

CVE-2026-64382 describes a Linux kernel SMB client-use-after-free issue in SMB2_open() replay handling. The vulnerability arises because a response-bearing SMB2_open attempt could return a replayable error and free its response buffer; if SMB2_open_init() fails before the next send, cleanup may f...

CVE-2026-64350

CVE-2026-64350 describes a memory leak in the Linux kernel USB cdnsp driver. The function cdnsp_alloc_stream_info() allocates stream_info->stream_ctx_array via cdnsp_alloc_stream_ctx() . If a later stream ring allocation or stream mapping update fails, the error path currently frees the alloca...

CVE-2026-64342 USB: iowarrior: fix use-after-free on disconnect

In the Linux kernel, the following vulnerability has been resolved: USB: iowarrior: fix use-after-free on disconnect Submitted write URBs are not stopped on close and therefore need to be stopped unconditionally on disconnect to avoid use-after-free in the completion handler...

CVE-2026-64333

The CVE-2026-64333 issue affects the Linux kernel USB serial driver digi_acceleport. The vulnerability was caused by digi_write_inb_command() not properly handling timeouts: it could update the transfer buffer and resubmit the URB on timeout, and for break-control type commands with no timeout it...

CVE-2026-64279

CVE-2026-64279 concerns the Linux kernel i2c core: a race in adapter deregistration where an adapter may be accessed after resources are freed. The fix removes the adapter from the IDR before tearing it down during deregistration or on registration failure to prevent use-after-free of resources s...

CVE-2026-64264

In CVE-2026-64264, the Linux kernel fuse-uring path is affected: copy_from_user can leave a positive residual in err, then -EFAULT is overwritten by fuse_uring_req_end, causing an incorrect success path and potentially uninitialised req->out.args. The fix assigns err = -EFAULT in the failure b...
