https://notcve.org/view.php?id=CVE-2024-42073
In the Linux kernel, the following vulnerability has been resolved: 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.

https://notcve.org/view.php?id=CVE-2024-42070
In the Linux kernel, the following vulnerability has been resolved: netfilter: nf_tables: fully validate NFT_DATA_VALUE on store to data registers register store validation for NFT_DATA_VALUE is conditional, however, the datatype is always either NFT_DATA_VALUE or NFT_DATA_VERDICT. This only requires a new helper function to infer the register type from the set datatype so this conditional check can be removed. Otherwise, pointer to chain object can be leaked through the registers. • https://git.kernel.org/stable/c/96518518cc417bb0a8c80b9fb736202e28acdf96 https://git.kernel.org/stable/c/40188a25a9847dbeb7ec67517174a835a677752f https://git.kernel.org/stable/c/23752737c6a618e994f9a310ec2568881a6b49c4 https://git.kernel.org/stable/c/5d43d789b57943720dca4181a05f6477362b94cf https://git.kernel.org/stable/c/461302e07f49687ffe7d105fa0a330c07c7646d8 https://git.kernel.org/stable/c/efb27ad05949403848f487823b597ed67060e007 https://git.kernel.org/stable/c/952bf8df222599baadbd4f838a49c4fef81d2564 https://git.kernel.org/stable/c/41a6375d48deaf7f730304b5153848bfa • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
