Published: 2009-01-15 · updated 2026-06-16
Weakness: CWE-20

Description

The ABI in the Linux kernel 2.6.28 and earlier on s390, powerpc, sparc64, and mips 64-bit platforms requires that a 32-bit argument in a 64-bit register was properly sign extended when sent from a user-mode application, but cannot verify this, which allows local users to cause a denial of service (crash) or possibly gain privileges via a crafted system call.

Affected products

Debian Linux: 4.0, 5.0
Linux kernel: through 2.6.28
