| Vector | AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H |
Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
The issue is related to the SUNRPC component in the Linux kernel, where the RPC client can clean up freed pipefs dentries. In certain scenarios, when the kernel frees the pipefs sb of the current client and immediately allocates a new pipefs sb, the rpc remove pipedir function may misjudge the existence of pipefs sb, leading to the cleaning of released freed pipefs dentries. This error can be caught by KASAN. The function
rpc remove pipedir should check whether the current pipefs sb is consistent with the original pipefs sb to fix this issue.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
