发布于3月6日3月6日 Members VMware Photon OS: CVE-2023-52619 Severity 4 CVSS (AV:L/AC:M/Au:N/C:P/I:P/A:P) Published 03/18/2024 Created 01/21/2025 Added 01/20/2025 Modified 01/20/2025 Description In the Linux kernel, the following vulnerability has been resolved: pstore/ram: Fix crash when setting number of cpus to an odd number When the number of cpu cores is adjusted to 7 or other odd numbers, the zone size will become an odd number. The address of the zone will become: addr of zone0 = BASE addr of zone1 = BASE + zone_size addr of zone2 = BASE + zone_size*2 ... The address of zone1/3/5/7 will be mapped to non-alignment va. Eventually crashes will occur when accessing these va. So, use ALIGN_DOWN() to make sure the zone size is even to avoid this bug.
