Description
A vulnerability in the Linux kernel's BPF subsystem allowed references to the main program via BPF_PSEUDO_FUNC to bypass address rewriting, potentially causing function calls to invalid addresses. This was fixed by rejecting BPF_PSEUDO_FUNC loads for the main subprogram, preventing such invalid references.
