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

Description: The issue is related to errors in resource management in the Linux kernel's bpf component. Exploitation of this issue can lead to a denial of service. The problem arises when task pt regs() returns NULL on powerpc for kernel threads, which is then used in bpf get stack() to check for user mode, resulting in a kernel oops. The fix involves checking the return value of task pt regs() before trying to obtain the call chain.

Recommendations: At the moment, there is no information about a newer version that contains a fix for this vulnerability.
