Summary
linux-aws, linux-aws-5.15, linux-gke vulnerabilities
Details

Zheng Wang discovered that the Broadcom FullMAC WLAN driver in the Linux kernel contained a race condition during device removal, leading to a use- after-free vulnerability. A physically proximate attacker could possibly use this to cause a denial of service (system crash). (CVE-2023-47233)

Several security issues were discovered in the Linux kernel. An attacker could possibly use these to compromise the system. This update corrects flaws in the following subsystems: - MAC80211 subsystem; - Tomoyo security module; (CVE-2024-26622, CVE-2023-52530)
