Description

A flaw was found in the Linux kernel, specifically affecting the LoongArch architecture. The system call (syscall) dispatch table, which handles requests from user programs, does not properly validate the syscall number provided by userspace. This missing boundary check could allow a local attacker to access memory outside the intended syscall function pointer tables, potentially leading to information disclosure.

Mitigation

No mitigation is specified in collected source.
