The vulnerability of the bpf component in the Linux operating system’s kernel allows a hacker to trigger a service failure.
The vulnerability of the bpf component in the Linux operating system’s kernel is related to errors in reading data beyond the buffer boundaries in the checkstackaccesswithinbounds function. Exploiting this vulnerability can allow an attacker to cause a service failure...
Vulnerability in the x86/bpf kernel components of the Linux operating system, allowing a hacker to cause a service failure
The vulnerability in the x86/bpf kernel components of the Linux operating system is related to incorrect validation of input data in the emitcall function. Exploiting this vulnerability can allow an attacker to cause a service failure...

kernel: bpf: Protect against int overflow for stack access size
A flaw was found in the Linux kernel. An integer overflow vulnerability exists in the access size of a stack, such that the size of the access stack can appear negative as a result of overflowing its signed int representation. This issue can result in denial of service...
CVE-2024-50253 bpf: Check the validity of nr_words in bpf_iter_bits_new()
In the Linux kernel, the following vulnerability has been resolved: bpf: Check the validity of nrwords in bpfiterbitsnew Check the validity of nrwords in bpfiterbitsnew. Without this check, when multiplication overflow occurs for nrbits e.g., when nrwords = 0x0400-0001, nrbits becomes 64, stack...
