Linux BPF Unauthorized Access

The vulnerability of the BPF subsystem in Linux operating systems is related to deficiencies in the authentication mechanism. Exploiting this vulnerability can allow an attacker to gain unauthorized access to protected information...

CVE-2021-33624

A flaw was found in the Linux kernel's BPF subsystem, where protection against speculative execution attacks Spectre mitigation can be bypassed. The highest threat from this vulnerability is to confidentiality. Mitigation The default Red Hat Enterprise Linux kernel setting prevents unprivileged...

CVE-2021-3489

A flaw out of bound memory write in the Linux kernel BPF subsystem was found in the way user writes to BPF ring buffer too fast, so larger buffer than available memory could be allocated. A local user could use this flaw to crash the system or possibly escalate their privileges on the system...
