CVE-2026-31413-BPF-Container-Escape

CVE-2026-31413: Un Byte en el Verificador BPF para Escape de Contenedor Encontré un bug de solidez en el verificador BPF de Linux: un + 1 en una llamada pushstack que hace que el verificador omita una instrucción ALU en una ruta bifurcada. Para BPFOR, esto significa que el verificador rastrea dst...

CVE-2020-8835

CVE-2020-8835 En el kernel de Linux 5.5.0 y posteriores, el verificador de BPF kernel/bpf/verifier.c no restringe correctamente los límites de los registros para operaciones de 32 bits, lo que provoca lecturas y escrituras fuera de los límites en la memoria del kernel. Esta vulnerabilidad también...

CentOS Linux 7 [TuxCare] Security Update: bpftool / kernel / kernel-debug / kernel-debug-devel / kernel-devel / etc Multiple Vulnerabilities (CENTOS7:CLSA-2026:1787291758)

The CentOS Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the TuxCare CENTOS7:CLSA-2026:1787291758 advisory. - The bpf verifier in the Linux kernel did not properly handle mod32 destination register truncation when the source register was known ...

CVE-2026-93125

A flaw was found in the Linux kernel's BPF Berkeley Packet Filter verifier. This vulnerability occurs because the verifier does not correctly handle certain buffer size arguments, allowing values larger than a 32-bit integer. When these oversized values are processed, they are truncated, leading ...

CVE-2026-98060

A flaw was found in the Linux kernel. A local user with permissions to load Berkeley Packet Filter BPF programs can cause a Denial of Service DoS or potentially achieve privilege escalation. The BPF verifier fails to prevent resilient lock operations within red-black tree comparison callbacks,...

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-2026-98044

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-2026-98039

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-2026-98037

A flaw was found in the Linux kernel's Berkeley Packet Filter BPF verifier. An improper validation check fails to reject untrusted allocated-object pointers after their protection scope expires, incorrectly recognizing them as valid live objects. A local user with permissions to load BPF programs...

CVE-2026-98019

A flaw was found in the Linux kernel's Berkeley Packet Filter BPF verifier. The verifier failed to mark scalar registers as precise when checking null function arguments and specific helper call parameters, causing its state-tracking logic to improperly prune verification paths. A local attacker...

CVE-2026-98151

A flaw was found in the Linux kernel's BPF Berkeley Packet Filter verifier. A local user can trigger a Denial of Service DoS or kernel verification failure by loading a specially crafted BPF program containing speculative pointer arithmetic. This issue occurs because register subregister bounds a...

CVE-2026-98134

A flaw was found in the Linux kernel's Berkeley Packet Filter BPF verifier. During pointer register comparisons, the verifier can incorrectly deduce that a pointer cannot be null when it can actually be null at runtime. A local user with permissions to load BPF programs could exploit this flaw by...

CVE-2026-98132

A flaw was found in the Linux kernel's Berkeley Packet Filter BPF verifier. A local attacker with permission to load BPF programs could exploit this flaw to achieve privilege escalation or cause a Denial of Service DoS. This issue arises when the verifier improperly handles scalar values stored o...
