Linux BPF devmap Heap Buffer Overflow DoS

The vulnerability of the devmapinitmap function in the kernel/bpf/devmap.c module of the Linux kernel’s BPF subsystem is related to integer overflow. Exploiting this vulnerability could allow an attacker to compromise the confidentiality, integrity, and accessibility of the protected information...

SUSE CVE-2021-20268

An out-of-bounds access flaw was found in the Linux kernel's implementation of the eBPF code verifier in the way a user running the eBPF script calls devmapinitmap or sockmapalloc. This flaw allows a local user to crash the system or possibly escalate their privileges. The highest threat from thi...
