Description
Incorrect verifier pruning in BPF in Linux Kernel >=5.4 leads to unsafe
code paths being incorrectly marked as safe, resulting in arbitrary read/write in
kernel memory, lateral privilege escalation, and container escape.
An incorrect verifier pruning flaw was found in BPF in the Linux Kernel that may lead to unsafe code paths incorrectly marked as safe, resulting in arbitrary read/writes in kernel memory, lateral privilege escalation, and container escape.
