Description

A flaw was found in the Linux kernel, specifically within its BPF (Berkeley Packet Filter) subsystem. This vulnerability, a use-after-free, arises from incorrect reference counting in the `check_pseudo_btf_id()` function. It allows a local attacker to potentially corrupt memory, which could lead to privilege escalation or a system crash (denial of service).
