medium Nessus Plugin ID 248194
語言:
概要
Linux/Unix 主機上安裝的一個或多個套件存有弱點，供應商表示將不會修補。說明
Linux/Unix 主機上安裝了一個或多個受到弱點影響的套件，且供應商未提供可用的修補程式。- 已解決 Linux 核心中的下列弱點：mlxsw: spectrum_buffers: Fix memory corruptions on Spectrum-4 systems The following two shared buffer operations make use of the Shared Buffer Status Register (SBSR): # devlink sb occupancy snapshot pci/0000:01:00.0 # devlink sb occupancy clearmax pci/0000:01:00.0 The register has two masks of 256 bits to denote on which ingress / egress ports the register should operate on. Spectrum-4 has more than 256 ports, so the register was extended by cited commit with a new 'port_page' field. However, when filling the register's payload, the driver specifies the ports as absolute numbers and not relative to the first port of the port page, resulting in memory corruptions [1]. Fix by specifying the ports relative to the first port of the port page. [1] BUG: KASAN:
