CVE-2024-36921

En el kernel de Linux, se resolvió la siguiente vulnerabilidad: wifi: iwlwifi: mvm: proteger contra ID de STA no válido al eliminarlo Proteger contra ID de estación no válidos en iwl_mvm_mld_rm_sta_id ya que eso daría como resultado accesos a la matriz fuera de los límites. Esto evita problemas en caso de que el controlador entre en mal estado durante el manejo de errores.

An out-of-bounds memory access flaw was found in the Linux kernel’s Wireless WiFi Link Next-Gen AGN driver in how a user removes it. This flaw allows a local user to crash or potentially escalate their privileges on the system.

In the Linux kernel, the following vulnerability has been resolved: wifi: iwlwifi: mvm: guard against invalid STA ID on removal Guard against invalid station IDs in iwl_mvm_mld_rm_sta_id as that would result in out-of-bounds array accesses. This prevents issues should the driver get into a bad state during error handling.

Benedict Schlüter, Supraja Sridhara, Andrin Bertschi, and Shweta Shinde discovered that an untrusted hypervisor could inject malicious #VC interrupts and compromise the security guarantees of AMD SEV-SNP. This flaw is known as WeSee. A local attacker in control of the hypervisor could use this to expose sensitive information or possibly execute arbitrary code in the trusted execution environment. Several security issues were discovered in the Linux kernel. An attacker could possibly use these to compromise the system.
