Summary
linux-aws-hwe 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: - Block layer subsystem; - Userspace I/O drivers; - Ceph distributed file system; - Ext4 file system; - JFS file system; - NILFS2 file system; - Bluetooth subsystem; - Networking core; - IPv4 networking; - IPv6 networking; - Logical Link layer; - MAC80211 subsystem; - Netlink; - NFC subsystem; - Tomoyo security module; (CVE-2023-52524, CVE-2023-52530, CVE-2023-52601, CVE-2023-52439, CVE-2024-26635, CVE-2023-52602, CVE-2024-26614, CVE-2024-26704, CVE-2023-52604, CVE-2023-52566, CVE-2021-46981, CVE-2024-26622, CVE-2024-26735, CVE-2024-26805, CVE-2024-26801, CVE-2023-52583)
