| Vector | AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H |
Name of the Vulnerable Software and Affected Versions
Linux kernel version 4.18.0-425.3.1.el8.x86 64
Description
The vulnerability is related to a double free of
fcport in the qla2xxx driver, which can cause a server crash after LOGO. The issue arises because fcport is being freed twice, leading to an invalid opcode and a kernel bug. To resolve this, one of the free calls needs to be removed, and a check for a valid fcport should be added. Additionally, the qla2x00 free fcport() function should be used instead of kfree(). The vulnerability is associated with the qla2x00 els dcmd sp free() function and the qla2x00 issue logo() function.Recommendations
To resolve the issue, update the Linux kernel to a version that includes the fix for the double free of
fcport in the qla2xxx driver. Specifically, remove one of the free calls and add a check for a valid fcport. Also, use the qla2x00 free fcport() function instead of kfree().Note: At the moment, there is no information about a newer version that contains a fix for this vulnerability.
