Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. A security vulnerability exists in the Linux kernel that stems from an invalid progarray access issue in perfeventdetachbpfprog in the bpf, perf subsystem. No detailed...

Linux kernel 安全漏洞

Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. A security vulnerability exists in the Linux kernel that stems from a post-release reuse issue caused by a mismatch between the bpfprog and attachment RCU flavors in the bpf...

bpf Component DoS

The vulnerability of the bpf component in the Linux operating system’s kernel is related to the assignment of the NULL pointer. Exploiting this vulnerability can allow an attacker to cause a service failure...

Suricata BPF Filter DoS

The vulnerability of the BPF filter in the Suricata intrusion detection and prevention system is related to the operation leaving the buffer boundaries into memory. Exploiting this vulnerability can allow an attacker to cause a service failure...

kernel: bpf: Fix use-after-free in bpf_uprobe_multi_link_attach()

A flaw was found in the Linux kernel's extended Berkeley Packet Filter eBPF subsystem. A privileged local attacker, with CAPSYSADMIN capabilities or root access, could exploit a use-after-free vulnerability in the bpfuprobemultilinkattach function. This issue arises when bpflinkprime fails, leadi...

bpf Component DoS

The vulnerability of the bpf component in the Linux operating system’s kernel is related to errors in reading beyond the buffer boundaries. Exploiting this vulnerability can allow an attacker to cause a service failure...

OESA-2024-2502 bcc security update

BCC is a toolkit for creating efficient kernel tracing and manipulation programs, and includes several useful tools and examples. It makes use of extended BPF Berkeley Packet Filters, formally known as eBPF, a new feature that was first added to Linux 3.15. BCC makes BPF programs easier to write,...

Linux kernel 安全漏洞

Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. A security vulnerability exists in the Linux kernel that stems from a failure of the synclinkedregs function in the bpf subsystem to preserve the subregdef flag, which could le...

riscv and bpf components

The vulnerability of riscv and bpf components in Linux operating systems is related to the dereferencing of the NULL pointer. Exploiting this vulnerability can allow an attacker to cause a service failure...

OESA-2024-2492 kernel security update

The Linux Kernel, the operating system core itself. Security Fixes: In the Linux kernel, the following vulnerability has been resolved: bpf: support non-r10 register spill/fill to/from stack in precision tracking Use instruction jump history to record instructions that performed register spill/fi...

bpf Component DoS

The vulnerability of the bpf component in the Linux operating system’s kernel arises from an operation that goes beyond the buffer boundaries in memory. Exploiting this vulnerability can allow an attacker to cause a system failure...

kernel: bpf: Add BPF_PROG_TYPE_CGROUP_SKB attach type enforcement in BPF_LINK_CREATE

In the Linux kernel, the following vulnerability has been resolved: bpf: Add BPFPROGTYPECGROUPSKB attach type enforcement in BPFLINKCREATE bpfprogattach uses attachtypetoprogtype to enforce proper attach type for BPFPROGTYPECGROUPSKB. linkcreate uses bpfprogget and relies on...
