CVE-2026-43469

Summary: CVE-2026-43469 affects the Linux kernel xprtrdma component. The root cause is that rpcrdma_post_recvs() may exit early or fail to create a work request without decrementing ep->re_receiving. This miscount can cause rpcrdma_xprt_drain() to hang, leaving the completion blocked and poten...

CVE-2026-43429

CVE-2026-43429 (Linux kernel, USB usbtmc): The vulnerability arises from the usbtmc driver accepting user-specified timeouts that can be arbitrarily long for usb_bulk_msg() calls, potentially causing kernel threads to hang indefinitely. The issue is resolved by using usb_bulk_msg_killable() with ...

CVE-2026-43425

In the Linux kernel, the following vulnerability has been resolved: usb: image: mdc800: kill download URB on timeout mdc800deviceread submits downloadurb and waits for completion.

CVE-2026-43399

CVE-2026-43399 affects the Linux kernel amdgpu driver: a reference leak in amdgpu_userq_wait_ioctl occurs when an ioctl is aborted because the output array is too small. The fix drops references to syncobj and timeline fence during abort, and is cherry-picked from commit 68951e9c3e6bb22396bc42ef2...

CVE-2026-43398

The CVE-2026-43398 entry concerns the Linux kernel amdgpu driver. A vulnerability arises from improper input validation in the userq_wait ioctl (amdgpu_userq_wait_ioctl), where excessively large input values can cause an Out-Of-Memory (OOM) situation, leading to Denial of Service. The root cause ...
