CVE-2026-98075

A flaw was found in the Linux kernel's BPF Berkeley Packet Filter subsystem. When a BPF program references its main function as a callback, the kernel fails to translate the function reference into a valid memory address. A local user with permissions to load BPF programs could exploit this...

CVE-2026-98065

A flaw was found in the Linux kernel's BPF Berkeley Packet Filter subsystem. A local user can cause a Denial of Service DoS by creating a hash map lacking key type information and reading it through the BPF file system. Due to missing validation of BPF Type Format BTF metadata, the kernel attempt...

CVE-2026-98063

A flaw was found in the Linux kernel's BPF Berkeley Packet Filter subsystem. When formatting data using BPF Type Format BTF, the kernel attempts to access type identifiers without checking if they are initialized. A local user with permissions to execute BPF programs can exploit this vulnerabilit...

CVE-2026-98062

A flaw was found in the Linux kernel's Berkeley Packet Filter BPF subsystem. The kernel incorrectly treats certain signal tracepoint arguments as trusted memory pointers, even when special non-pointer indicator values are passed during signal delivery. A local user with privileges to attach BPF...

CVE-2026-98059

A flaw was found in the Linux kernel's BPF Berkeley Packet Filter subsystem. This issue allows a local attacker to cause a Denial of Service DoS through a system crash. The vulnerability occurs because the BPF verifier fails to recognize that process-wait tracepoint arguments can be null,...

CVE-2026-98058

A flaw was found in the Linux kernel's BPF Berkeley Packet Filter subsystem. Certain internal helper functions that pause execution to perform blocking operations were not properly marked as sleepable. A local user with permissions to load BPF programs can invoke these functions within...

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,...

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 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 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 : 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...

Important: kernel6.18

Issue Overview: 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 been resolved: libceph: bound pgtemp,upmap,upmapitems length to CEPHPGMAXSIZE CVE-2026-6815...

SUSE CVE-2026-98019

In the Linux kernel, the following vulnerability has been resolved: bpf: mark a NULL call argument precise checkfuncarg allows bpfregisterisnull for nullable arguments w/o marking the underlying scalar register precise. Hence a checkpoint created on such a path would prune against arbitrary scala...

SUSE CVE-2026-100074

In the Linux kernel, the following vulnerability has been resolved: bpf: Mark bpfrefcount field as unique BPFREFCOUNT is not marked as a unique field, while it should be. Fix this oversight...

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...
