Linux Distros Unpatched Vulnerability : CVE-2022-49376

medium Nessus Plugin ID 225393

Synopsis

The Linux/Unix host has one or more packages installed with a vulnerability that the vendor indicates will not be patched.

Description

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

 - In the Linux kernel, the following vulnerability has been resolved: scsi: sd: Fix potential NULL pointer dereference If sd_probe() sees an early error before sdkp->device is initialized, sd_zbc_release_disk() is called. This causes a NULL pointer dereference when sd_is_zoned() is called inside that function. Avoid this by removing the call to sd_zbc_release_disk() in sd_probe() error path. This change is safe and does not result in zone information memory leakage because the zone information for a zoned disk is allocated only when sd_revalidate_disk() is called, at which point sdkp->disk_dev is fully set, resulting in sd_disk_release() being called when needed to cleanup a disk zone information using sd_zbc_release_disk().
 (CVE-2022-49376)

Note that Nessus relies on the presence of the package as reported by the vendor.

Solution

There is no known solution at this time.
