Detailed vulnerability description
The vulnerability allows a local attacker to obtain potentially sensitive information on the target system.
The weakness exists due to kernel/bpf/verifier.c in the Linux kernel mishandles states_equal comparisons between the pointer data type and the UNKNOWN_VALUE data type. A local attacker can trigger a memory leak and obtain potentially sensitive address information.
