CVE-2010-1451

LOW 2.1EPSS 0.52%

Does this matter?

Lower severity and a low EPSS score (0.52%). Track it; it rarely justifies an emergency change on its own.

Description

The TSB I-TLB load implementation in arch/sparc/kernel/tsb.S in the Linux kernel before 2.6.33 on the SPARC platform does not properly obtain the value of a certain _PAGE_EXEC_4U bit and consequently does not properly implement a non-executable stack, which makes it easier for context-dependent attackers to exploit stack-based buffer overflows via a crafted application.
