{"id":"DEBIAN-CVE-2024-26710","details":"In the Linux kernel, the following vulnerability has been resolved:  powerpc/kasan: Limit KASAN thread size increase to 32KB  KASAN is seen to increase stack usage, to the point that it was reported to lead to stack overflow on some 32-bit machines (see link).  To avoid overflows the stack size was doubled for KASAN builds in commit 3e8635fb2e07 (\"powerpc/kasan: Force thread size increase with KASAN\").  However with a 32KB stack size to begin with, the doubling leads to a 64KB stack, which causes build errors:   arch/powerpc/kernel/switch.S:249: Error: operand out of range (0x000000000000fe50 is not between 0xffffffffffff8000 and 0x0000000000007fff)  Although the asm could be reworked, in practice a 32KB stack seems sufficient even for KASAN builds - the additional usage seems to be in the 2-3KB range for a 64-bit KASAN build.  So only increase the stack for KASAN if the stack size is \u003c 32KB.","modified":"2026-09-15T09:03:05.014027533Z","published":"2024-04-03T15:15:53.487Z","upstream":["CVE-2024-26710"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2024-26710"}],"affected":[{"package":{"name":"linux","ecosystem":"Debian:13","purl":"pkg:deb/debian/linux?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.8.9-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2024-26710.json"}},{"package":{"name":"linux","ecosystem":"Debian:14","purl":"pkg:deb/debian/linux?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.8.9-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2024-26710.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"}]}
