IA64: local DoS with corrupted ELFs
 
 This patch prevents cross-region mappings
 on IA64 and SPARC which could lead to system crash.
 
 davem@ confirmed: "This looks fine to me." :)

No patch is attached; not enough information is given about the vulnerability. Please reopen with additional information.

Umm, there is a patch. Look at the URL of this bug.
Comment 3 Tim Yamin (RETIRED) gentoo-dev 2006-10-28 05:53:42 UTC 
IA64 is fine, has 2.6.18 stabled. SPARC has gentoo-sources 2.6.17-r8 stabled which is fine, this is fixed usptream in 2.6.17.11. hardened-sources-2.6.17-r1 has genpatches r8 which also fixes this.

CVE-2006-4538:
Linux kernel 2.6.17 and earlier, when running on IA64 or SPARC platforms, allows local users to cause a denial of service (crash) via a malformed ELF file that triggers memory maps that cross region boundaries.
