UBUNTU-CVE-2022-3606
A vulnerability was found in Linux Kernel. It has been classified as problematic. This affects the function findprogbysecinsn of the file tools/lib/bpf/libbpf.c of the component BPF. The manipulation leads to null pointer dereference. It is recommended to apply a patch to fix this issue. The...
CVE-2022-2785
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...

PUB-A-215814262
In kernel/bpf/verifier.c , there is a possible way to manipulate pointer arithmetic due to a logic error in the code. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation...
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-2021-45402
CVE-2021-45402 affects the Linux kernel where check_alu_op() in kernel/bpf/verifier.c does not update bounds properly when handling mov32, enabling local attackers to leak potentially sensitive addresses (pointer leak). The description is consistently cited across multiple connected advisories (e...
CVE-2018-25020
The BPF subsystem in the Linux kernel before 4.17 mishandles situations with a long jump over an instruction sequence where inner instructions require substantial expansions into multiple BPF instructions, leading to an overflow. This affects kernel/bpf/core.c and net/core/filter.c...

CVE-2019-7308
A bypass was found for the Spectre v1 hardening in the eBPF engine of the Linux kernel. The code in the kernel/bpf/verifier.c performs undesirable out-of-bounds speculation on pointer arithmetic in various cases, including cases of different branches with different state or limits to sanitize,...
CVE-2019-7308
CVE-2019-7308 affects the Linux kernel’s BPF verifier in kernel/bpf/verifier.c prior to 4.20.6. The issue is undesirable out-of-bounds speculation on pointer arithmetic across branches with different state/limits, enabling potential side-channel attacks. Public sources in connected documents cons...
CVE-2017-17857
The checkstackboundary function in kernel/bpf/verifier.c in the Linux kernel through 4.14.8 allows local users to cause a denial of service memory corruption or possibly have unspecified other impact by leveraging mishandling of invalid variable stack read operations...
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:...
