CVE-2024-43880

CVE-2024-43880 affects the Linux kernel mlxsw spectrum ACL (Spectrum-2 and newer). The vulnerability arises from how ACLs could be migrated between A-TCAM and C-TCAM using the objagg mask aggregation, where the driver and lib compared masks without respecting TCAM context, potentially creating ne...

kernel: mlxsw: spectrum_acl_tcam: Fix memory leak when canceling rehash work

CVE-2024-35852 addresses a memory leak in the Linux kernel's mlxsw driver, specifically within the Spectrum ACL TCAM module. The issue occurs when rehash work is canceled while pending, leading to allocated hints not being freed properly. This results in a memory leak that can degrade system...
