CVE-2026-43416

A flaw was found in the Linux kernel. A local user can cause a denial of service DoS by triggering a NULL pointer dereference within the perf subsystem. This occurs when the memory management structure current-mm is prematurely released before the system attempts to retrieve the user callchain,...

CVE-2026-43321

A flaw was found in the Linux kernel's Berkeley Packet Filter BPF subsystem. This vulnerability arises from the kernel's failure to correctly identify and mark active registers during indirect jump operations within the BPF program execution. An attacker could potentially exploit this to manipula...

CVE-2026-43306

A flaw was found in the Linux kernel's Berkeley Packet Filter BPF crypto component. A local attacker, by running a specially crafted BPF program, could trigger a type mismatch in function pointers when Control Flow Integrity CFI is enabled. This can lead to a kernel internal error, resulting in a...

In the Linux kernel, the following vulnerability has been resolved: bpf: Properly mark live registers for indirect jumps For a gotox rX instruction the rX register should be marked as used in the computeinsnliveregs function. Fix this...

CVE-2026-43416

In the Linux kernel, the following vulnerability has been resolved: powerpc, perf: Check that current-mm is alive before getting user callchain It may happen that mm is already released, which leads to kernel panic. This adds the NULL check for current-mm, similarly to commit 20afc60f892d "x86,...

The Linux kernel is the kernel used by the Linux operating system developed by the Linux Foundation in the United States. There is a security vulnerability in the Linux kernel. This vulnerability stems from the checkmemaccess function in the BPF module, which matches PTRTOBUF pointers using...

CVE-2026-43070

A flaw was found in the Linux kernel's BPF Berkeley Packet Filter verifier. The verifier fails to correctly reset a register's ID after a BPFEND byte swap operation. This oversight can lead to the verifier incorrectly propagating learned memory bounds to other registers, creating false confidence...

SUSE CVE-2026-43009

In the Linux kernel, the following vulnerability has been resolved: bpf: Fix incorrect pruning due to atomic fetch precision tracking When backtrackinsn encounters a BPFSTX instruction with BPFATOMIC and BPFFETCH, the src register or r0 for BPFCMPXCHG also acts as a destination, thus receiving th...

CVE-2026-43070

In the Linux kernel, the following vulnerability has been resolved: bpf: Reset register ID for BPFEND value tracking When a register undergoes a BPFEND byte swap operation, its scalar value is mutated in-place. If this register previously shared a scalar ID with another register e.g., after an r1...

CVE-2026-43070

The CVE describes a Linux kernel BPF verifier flaw: after a BPF_END (byte swap), dst_reg->id is not reset to 0, which can cause the verifier to propagate learned bounds to a linked register, creating a risk of out-of-bounds memory accesses. The concrete impact is potential privilege/escalation...

The vulnerability in the `src/libbpf.c` component of the BPF loader library allows a attacker to cause a service denial.

The vulnerability in the src/libbpf.c component of the BPF loader library in Libbpf is related to pointer dereferencing errors. Exploiting this vulnerability could allow an attacker to cause a system failure...
