Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
In the Linux kernel, the following vulnerability has been resolved: media: usbtv: Remove useless locks in usbtv_video_free() Remove locks calls in usbtv_video_free() because are useless and may led to a deadlock as reported here: https://syzkaller.appspot.com/x/bisect.txt?x=166dc872180000 Also remove usbtv_stop() call since it will be called when unregistering the device. Before 'c838530d230b' this issue would only be noticed if you disconnect while streaming and now it is noticeable even when disconnecting while not streaming.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis
How this class of weakness works · CWE-667

Shared resources are accessed without correct locking, so concurrent operations interleave into inconsistent — and sometimes exploitable — states, or deadlock the service outright. These bugs are subtle and timing-dependent. The fix is correct, consistent locking or atomic operations around every shared resource.

Recommended fix High confidence

Linux kernel 5.10.227, 5.15.168, 6.1.113, or 6.6.55 (depending on which branch you are on)

  1. Identify the currently running Linux kernel version using `uname -r`
  2. Determine which version branch your kernel belongs to (e.g., 5.10.x, 5.15.x, 6.1.x, 6.2.x, 6.6.x)
  3. Upgrade the Linux kernel to a fixed version: for 5.10.x branch upgrade to 5.10.227 or later; for 5.15.x branch upgrade to 5.15.168 or later; for 6.1.x branch upgrade to 6.1.113 or later; for 6.2.x through 6.6.x branch upgrade to 6.6.55 or later
  4. Update the kernel using your distribution's package manager (e.g., `apt-get update && apt-get install linux-image-<version>` for Debian/Ubuntu, or `yum update kernel` for RHEL/CentOS)
  5. Reboot the system to load the fixed kernel
  6. Verify the new kernel version is running with `uname -r`
Caveat Kernel upgrades may require rebooting the system and could have compatibility implications with custom kernel modules or specific driver requirements
