High
| Vector | AV:N/AC:L/Au:N/C:P/I:P/A:P |
Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
The issue is related to the PCI endpoint in the Linux kernel, specifically with the
pci epf test core init() function. Instead of getting epc features from the pci epc get features() API, the cached pci epf test::epc features value is used to avoid a NULL check. The NULL check is already performed in pci epf test bind(), making the additional check in pci epf test core init() redundant. A commit removed the "core init notifier" flag, leading to a false positive Smatch warning. The fix involves removing the redundant NULL check and using the epc features flags directly.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
