CVSS: 6.5EPSS: 0%CPEs: 3EXPL: 1CVE-2024-0564 – Kernel: max page sharing of kernel samepage merging (ksm) may cause memory deduplication
https://notcve.org/view.php?id=CVE-2024-0564
A flaw was found in the Linux kernel's memory deduplication mechanism. The max page sharing of Kernel Samepage Merging (KSM), added in Linux kernel version 4.4.0-96.119, can create a side channel. When the attacker and the victim share the same host and the default setting of KSM is "max page sharing=256", it is possible for the attacker to time the unmap to merge with the victim's page. The unmapping time depends on whether it merges with the victim's page and additional physical pages are created beyond the KSM's "max page share". Through these operations, the attacker can leak the victim's page. • https://access.redhat.com/security/cve/CVE-2024-0564 https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1680513 https://bugzilla.redhat.com/show_bug.cgi?id=2258514 https://link.springer.com/conference/wisa https://wisa.or.kr/accepted • CWE-99: Improper Control of Resource Identifiers ('Resource Injection') CWE-203: Observable Discrepancy •

In the Linux kernel before 6.4.5, drivers/gpu/drm/drm_atomic.c has a use-after-free during a race condition between a nonblocking atomic commit and a driver unload. En el kernel de Linux anterior a 6.4.5, drivers/gpu/drm/drm_atomic.c tiene un use-after-free durante una condición de ejecución entre un commit atómico sin bloqueo y una descarga del controlador. A flaw was found in the Linux kernel Direct Rendering Infrastructure (DRI) subsystem in which a use-after-free can be caused when a user triggers a race condition between a nonblocking atomic commit and a driver unload. A local user could use this flaw to crash the system or potentially escalate their privileges on the system. • https://cdn.kernel.org/pub/linux/kernel/v6.x/ChangeLog-6.4.5 https://github.com/torvalds/linux/commit/4e076c73e4f6e90816b30fcd4a0d7ab365087255 https://access.redhat.com/security/cve/CVE-2023-51043 https://bugzilla.redhat.com/show_bug.cgi?id=2260005 • CWE-416: Use After Free •
