Important: libpcap

Issue Overview: In BPF instructions that load/store a value from/to a scratch memory register the register index is an unsigned 32-bit integer and must not exceed 15, but libpcap BPF interpreter does not validate the value. In particular uncommon use cases a crafted filter program can cause the...

Amazon Linux 2 : libpcap (ALAS-2026-3927)

The version of libpcap installed on the remote host is prior to 1.5.3-11. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2026-3927 advisory. In BPF instructions that load/store a value from/to a scratch memory register the register index is an unsigned 32-bit...

Amazon Linux 2023 : libpcap, libpcap-devel (ALAS2023-2026-3100)

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2026-3100 advisory. In BPF instructions that load/store a value from/to a scratch memory register the register index is an unsigned 32-bit integer and must not exceed 15, but libpcap BPF interpreter does not...

Amazon Linux 2023 : bpftool6.18, kernel6.18, kernel6.18-devel (ALAS2023-2026-3139)

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2026-3139 advisory. In the Linux kernel, the following vulnerability has been resolved: libceph: fix two unsafe bare decodes in decodelockers CVE-2026-68082 In the Linux kernel, the following vulnerability has be...

CVE-2026-98049

A flaw was found in the Linux kernel's BPF Berkeley Packet Filter subsystem. When executing a 32-bit atomic compare-and-exchange operation on arena memory, the kernel fails to properly clear zero-extend the upper half of the target register as required by BPF specifications. A local attacker with...

CVE-2026-98048

A flaw was found in the Linux kernel's BPF Berkeley Packet Filter verifier. This vulnerability may allow a local user to achieve privilege escalation or cause a Denial of Service DoS through memory corruption. During helper call optimizations, the verifier improperly rewrites instruction sequence...

CVE-2026-98047

A flaw was found in the Linux kernel's BPF Berkeley Packet Filter verifier, which may allow a local attacker to cause a denial of service DoS or potentially escalate privileges. When verifying red-black tree rbtree callbacks, the verifier fails to enforce callback restrictions across nested...

CVE-2026-98046

A flaw was found in the Linux kernel's BPF Berkeley Packet Filter subsystem. The bpfbtffindbynamekind helper function was not properly marked as sleepable capable of pausing execution while waiting for resources, allowing it to be executed in non-sleepable contexts such as timer callbacks. A loca...

CVE-2026-98045

A flaw was found in the Linux kernel's BPF Berkeley Packet Filter subsystem. Certain stack retrieval helper functions can perform blocking filesystem operations, but were not properly marked as sleepable. A local user with permission to load BPF programs could exploit this flaw by invoking these...

CVE-2026-98044

A flaw was found in the Linux kernel's BPF Berkeley Packet Filter verifier. This issue allows a privileged local user to cause a Denial of Service DoS or unexpected program rejection by loading a specially crafted BPF program containing legacy packet-load instructions inside callback functions. D...

CVE-2026-98043

A flaw was found in the Linux kernel's Berkeley Packet Filter BPF verifier. The verifier incorrectly assumes that certain pointer types are non-null without accounting for unbounded offsets that can wrap around to zero at runtime. A local user with permissions to load BPF programs can exploit thi...

CVE-2026-98042

A flaw was found in the Linux kernel's Berkeley Packet Filter BPF verifier. A local user with permissions to load BPF programs could exploit this vulnerability to achieve privilege escalation or cause a denial of service DoS. The issue stems from improper handling of register states during...

CVE-2026-98041

A flaw was found in the Linux kernel's Berkeley Packet Filter BPF verifier. The verifier incorrectly predicts that 32-bit conditional branch comparisons between a pointer and zero are always taken, failing to account for valid pointer values whose lower 32 bits can be zero. A local attacker could...

CVE-2026-98040

A flaw was found in the Linux kernel's Berkeley Packet Filter BPF verifier. When validating conditional jump operations using register comparisons against null values, the verifier fails to properly track register precision across different execution paths. A local user capable of loading BPF...

CVE-2026-98039

A flaw was found in the Linux kernel's BPF Berkeley Packet Filter verifier. The verifier improperly validates pointer types when storing values into per-CPU map fields, allowing standard memory allocations or kernel pointers to be accepted as per-CPU data. A local user with permissions to load BP...

CVE-2026-98038

A flaw was found in the Linux kernel's Berkeley Packet Filter BPF subsystem. When validating programs that manage shared reference-counted objects, the BPF verifier incorrectly treats borrowed references as always valid and fails to require null-pointer checks. A local user can exploit this...
