Linux maybe_fork_scalars Heap Buffer Overflow DoS

The vulnerability of the maybeforkscalars function in the Linux operating system’s kernel is related to the execution of operations outside of the buffer in memory. Exploiting this vulnerability could allow an attacker to influence the confidentiality, integrity, and accessibility of the protecte...

CVE-2026-31413

In the Linux kernel, the following vulnerability has been resolved: bpf: Fix unsound scalar forking in maybeforkscalars for BPFOR maybeforkscalars is called for both BPFAND and BPFOR when the source operand is a constant. When dst has signed range -1, 0, it forks the verifier state: the pushed pa...

Linux Kernel Security Vulnerabilities

The Linux kernel is the kernel used by the Linux operating system developed by the Linux Foundation in the United States. There is a security vulnerability in the Linux kernel, which stems from a scalar fork logic error in the BPFOR instruction within the maybeforkscalars function. This error may...
