There exists an arbitrary memory read within the Linux Kernel BPF - Constants provided to fill pointers in structs passed in to bpfsysbpf are not verified and can point anywhere, including memory not owned by BPF. An attacker with CAPBPF can arbitrarily read memory from anywhere on the system. We...

UBUNTU-CVE-2022-0500

A flaw was found in unrestricted eBPF usage by the BPFBTFLOAD, leading to a possible out-of-bounds memory write in the Linux kernel’s BPF subsystem due to the way a user loads BTF. This flaw allows a local user to crash or escalate their privileges on the system...

CVE-2014-3145

The BPFSANCNLATTRNEST extension implementation in the skrunfilter function in net/core/filter.c in the Linux kernel through 3.14.3 uses the reverse order in a certain subtraction, which allows local users to cause a denial of service over-read and system crash via crafted BPF instructions. NOTE:...
