| Vector | AV:L/AC:L/Au:S/C:N/I:N/A:C |
Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
A flaw exists in the Linux kernel’s scsi subsystem, specifically within the qla2xxx driver. The issue involves improper memory freeing of items allocated for processing I/O control blocks (IOCBs). The
qla24xx alloc purex item() function can return a pre-allocated item instead of dynamically allocating memory. Subsequently, the qla2xxx process purls iocb() function incorrectly uses kfree() to release these pre-allocated items, leading to potential memory corruption. The fix involves using the correct deallocation function, qla24xx free purex item(), to handle both dynamically allocated and pre-allocated items correctly.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
