| Vector | AV:N/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
The issue is related to a possible use-after-free in the
wdt turnoff() function of the sc520 wdt module. The problem occurs because the del timer() function does not wait for the timer handler to finish, which can lead to a use-after-free situation. This is fixed by calling del timer sync(), ensuring the timer handler has finished and cannot re-schedule itself.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
