CVE-2025-21843

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A issue in the Linux kernel has been identified where the priorities info variable is uninitialized. This uninitialized value is then copied to a user object when the PANTHOR UOBJ SET() function is called, potentially leading to unexpected behavior. The problem arises from a garbage value in the panthor ioctl dev query() function.

Recommendations To resolve this issue, initialize the priorities info variable using memset to avoid the garbage value problem. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
