AI-analyzed exploit summary This exploit targets a Linux kernel vulnerability (CVE-2003-0961) in the do_brk system call, allowing local privilege escalation by manipulating memory mappings and LDT entries to execute arbitrary kernel code.
Description
Integer overflow in the do_brk function for the brk system call in Linux kernel 2.4.22 and earlier allows local users to gain root privileges.
Exploits (2)
This exploit targets a Linux kernel vulnerability (CVE-2003-0961) in the do_brk system call, allowing local privilege escalation by manipulating memory mappings and LDT entries to execute arbitrary kernel code.
This exploit leverages a vulnerability in the Linux kernel's `brk` system call to bypass memory checks by using a high virtual address. It also relocates the stack to ensure successful exploitation, targeting local privilege escalation (LPE).
