CVE-2024-26932

CVSS v3.1

7.8

High

VectorAV: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 versions prior to 6.8.0-rc5-next-20240220-05616-g52728c567a55
Description The issue is related to a double-free problem in the tcpm port unregister pd() function. When unregistering pd capabilities in tcpm, KASAN captures a double-free issue. The root cause is that the same capability is freed twice, first by pd capabilities release() and then explicitly by tcpm port unregister pd(). This can lead to a denial of service or other unspecified impact.
Recommendations To fix the issue, remove the kree() call from tcpm port unregister pd(). At the moment, there is no information about a newer version that contains a fix for this vulnerability.
