SUSE CVE-2019-7308

kernel/bpf/verifier.c in the Linux kernel before 4.20.6 performs undesirable out-of-bounds speculation on pointer arithmetic in various cases, including cases of different branches with different state or limits to sanitize, leading to side-channel attacks...

SUSE CVE-2020-8835

In the Linux kernel 5.5.0 and newer, the bpf verifier kernel/bpf/verifier.c did not properly restrict the register bounds for 32-bit operations, leading to out-of-bounds reads and writes in kernel memory. The vulnerability also affects the Linux 5.4 stable series, starting with v5.4.7, as the...

SUSE CVE-2020-27171

An issue was discovered in the Linux kernel before 5.11.8. kernel/bpf/verifier.c has an off-by-one error with a resultant integer underflow affecting out-of-bounds speculation on pointer arithmetic, leading to side-channel attacks that defeat Spectre mitigations and obtain sensitive information...

SUSE CVE-2020-27170

An issue was discovered in the Linux kernel before 5.11.8. kernel/bpf/verifier.c performs undesirable out-of-bounds speculation on pointer arithmetic, leading to side-channel attacks that defeat Spectre mitigations and obtain sensitive information from kernel memory, aka CID-f232326f6966. This...

SUSE CVE-2020-27194

An issue was discovered in the Linux kernel before 5.8.15. scalar32minmaxor in kernel/bpf/verifier.c mishandles bounds tracking during use of 64-bit values, aka CID-5b9fbeb75b6a...

SUSE CVE-2021-20239

A flaw was found in the Linux kernel in versions before 5.4.92 in the BPF protocol. This flaw allows an attacker with a local account to leak information about kernel internal addresses. The highest threat from this vulnerability is to confidentiality...

SUSE CVE-2021-29648

An issue was discovered in the Linux kernel before 5.11.11. The BPF subsystem does not properly consider that resolvedids and resolvedsizes are intentionally uninitialized in the vmlinux BPF Type Format BTF, which can cause a system crash upon an unexpected access attempt in mapcreate in...

SUSE CVE-2021-29649

An issue was discovered in the Linux kernel before 5.11.11. The user mode driver UMD has a copyprocess memory leak, related to a lack of cleanup steps in kernel/usermodedriver.c and kernel/bpf/preload/bpfpreloadkern.c, aka CID-f60a85cad677...

SUSE CVE-2021-31829

kernel/bpf/verifier.c in the Linux kernel through 5.12.1 performs undesirable speculative loads, leading to disclosure of stack content via side-channel attacks, aka CID-801c6058d14a. The specific concern is not protecting the BPF stack area against speculative loads. Also, the BPF stack can...

SUSE CVE-2021-35477

In the Linux kernel through 5.13.7, an unprivileged BPF program can obtain sensitive information from kernel memory via a Speculative Store Bypass side-channel attack because a certain preempting store operation does not necessarily occur before a store operation that has an attacker-controlled...

SUSE CVE-2021-45941

libbpf 0.6.0 and 0.6.1 has a heap-based buffer overflow 8 bytes in bpfobjectopen called from bpfobjectopenmem and bpf-object-fuzzer.c...

SUSE CVE-2022-0433

A NULL pointer dereference flaw was found in the Linux kernel's BPF subsystem in the way a user triggers the mapgetnextkey function of the BPF bloom filter. This flaw allows a local user to crash the system. This flaw affects Linux kernel versions prior to 5.17-rc1...

SUSE 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...

SUSE CVE-2022-2905

An out-of-bounds memory read flaw was found in the Linux kernel's BPF subsystem in how a user calls the bpftailcall function with a key larger than the maxentries of the map. This flaw allows a local user to gain unauthorized access to data...

SUSE CVE-2022-3594

A vulnerability was found in Linux Kernel. It has been declared as problematic. Affected by this vulnerability is the function intrcallback of the file drivers/net/usb/r8152.c of the component BPF. The manipulation leads to logging of excessive data. The attack can be launched remotely. It is...

SUSE CVE-2022-3623

A vulnerability was found in Linux Kernel. It has been declared as problematic. Affected by this vulnerability is the function followpagepte of the file mm/gup.c of the component BPF. The manipulation leads to race condition. The attack can be launched remotely. It is recommended to apply a patch...

SUSE CVE-2022-23222

kernel/bpf/verifier.c in the Linux kernel through 5.15.14 allows local users to gain privileges because of the availability of pointer arithmetic via certain ORNULL pointer types...
