CVSS: 5.5EPSS: 0%CPEs: 8EXPL: 0CVE-2023-52619 – pstore/ram: Fix crash when setting number of cpus to an odd number
https://notcve.org/view.php?id=CVE-2023-52619
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. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: pstore/ram: soluciona el fallo al establecer el número de CPU en un número impar. Cuando el número de núcleos de CPU se ajusta a 7 u otros números impares, el tamaño de la zona se convertirá en un número impar. La dirección de la zona se convertirá en: dirección de zona0 = BASE dirección de zona1 = BASE + tamaño_zona dirección de zona2 = BASE + tamaño_zona*2 ... La dirección de zona1/3/5/7 se asignará a va no alineada . • https://git.kernel.org/stable/c/8b69c30f4e8b69131d92096cb296dc1f217101e4 https://git.kernel.org/stable/c/e9f6ac50890104fdf8194f2865680689239d30fb https://git.kernel.org/stable/c/a63e48cd835c34c38ef671d344cc029b1ea5bf10 https://git.kernel.org/stable/c/2a37905d47bffec61e95d99f0c1cc5dc6377956c https://git.kernel.org/stable/c/75b0f71b26b3ad833c5c0670109c0af6e021e86a https://git.kernel.org/stable/c/0593cfd321df9001142a9d2c58d4144917dff7ee https://git.kernel.org/stable/c/cd40e43f870cf21726b22487a95ed223790b3542 https://git.kernel.org/stable/c/d49270a04623ce3c0afddbf3e984cb245 • CWE-99: Improper Control of Resource Identifiers ('Resource Injection') •
