Detailsinfo

A vulnerability classified as critical has been found in Linux Kernel up to 6.12.1. This affects the function qedi_alloc_and_init_sb of the component scsi. The manipulation with an unknown input leads to a memory leak vulnerability. CWE is classifying the issue as CWE-401. The product does not sufficiently track and release allocated memory after it has been used, which slowly consumes remaining memory. This is going to have an impact on availability. The summary by CVE is:

In the Linux kernel, the following vulnerability has been resolved: scsi: qedi: Fix a possible memory leak in qedi_alloc_and_init_sb() Hook "qedi_ops->common->sb_init = qed_sb_init" does not release the DMA memory sb_virt when it fails. Add dma_free_coherent() to free it. This is the same way as qedr_alloc_mem_sb() and qede_alloc_mem_sb().

It is possible to read the advisory at git.kernel.org. This vulnerability is uniquely identified as CVE-2024-56747 since 12/29/2024. Technical details of the vulnerability are known, but there is no available exploit.

The vulnerability scanner Nessus provides a plugin with the ID 214901 (SUSE SLES15 Security Update : kernel (SUSE-SU-2025:0289-1)), which helps to determine the existence of the flaw in a target environment.
