Detailsinfo

A vulnerability was found in Linux Kernel up to 6.1.112/6.6.56/6.11.3 and classified as problematic. Affected by this issue is some unknown processing of the component DA_ID Handler. The manipulation with an unknown input leads to a race condition vulnerability. Using CWE to declare the problem leads to CWE-362. The product contains a code sequence that can run concurrently with other code, and the code sequence requires temporary, exclusive access to a shared resource, but a timing window exists in which the shared resource can be modified by another code sequence that is operating concurrently. The impact remains unknown. CVE summarizes:

In the Linux kernel, the following vulnerability has been resolved: scsi: lpfc: Ensure DA_ID handling completion before deleting an NPIV instance Deleting an NPIV instance requires all fabric ndlps to be released before an NPIV's resources can be torn down. Failure to release fabric ndlps beforehand opens kref imbalance race conditions. Fix by forcing the DA_ID to complete synchronously with usage of wait_queue.

The advisory is available at git.kernel.org. This vulnerability is handled as CVE-2024-50183 since 10/21/2024. The exploitation is known to be difficult. The technical details are unknown and an exploit is not available.
