Detailsinfo

A vulnerability was found in Linux Kernel up to 6.8.5. It has been declared as critical. Affected by this vulnerability is the function lpfc_rcv_padisc of the component scsi. The manipulation with an unknown input leads to a memory leak vulnerability. The CWE definition for the vulnerability is CWE-401. The product does not sufficiently track and release allocated memory after it has been used, which slowly consumes remaining memory. As an impact it is known to affect availability. The summary by CVE is:

In the Linux kernel, the following vulnerability has been resolved: scsi: lpfc: Fix possible memory leak in lpfc_rcv_padisc() The call to lpfc_sli4_resume_rpi() in lpfc_rcv_padisc() may return an unsuccessful status. In such cases, the elsiocb is not issued, the completion is not called, and thus the elsiocb resource is leaked. Check return value after calling lpfc_sli4_resume_rpi() and conditionally release the elsiocb resource.

The advisory is shared at git.kernel.org. This vulnerability is known as CVE-2024-35930 since 05/17/2024. The exploitation appears to be difficult. Technical details are known, but no exploit is available.
