| Vector | AV:L/AC:L/Au:S/C:C/I:C/A:C |
Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
A memory corruption issue has been identified in the Linux kernel, specifically in the stmmac driver. The problem arises from accessing a freed
irq affinity hint, which is caused by the cpumask being a local variable. Its pointer is saved to irq desc and may be accessed from procfs. To address this, the persistent mask cpumask of(cpu#) should be used instead.Recommendations
To resolve this issue, update the Linux kernel to a version that includes the fix for accessing freed
irq affinity hint in the stmmac driver.
At the moment, there is no information about a newer version that contains a fix for this vulnerability.Exploit
