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)

Sander Wiebing, Alvise de Faveri Tron, Herbert Bos, and Cristiano Giuffrida
discovered that the Linux kernel mitigations for the initial Branch History
Injection vulnerability (CVE-2022-0001) were insufficient for Intel
processors. A local attacker could potentially use this to expose sensitive
information. (CVE-2024-2201)

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:

• Hardware random number generator core;
• Ext4 file system;
• JFS file system;
• Bluetooth subsystem;
• Networking core;
• IPv4 networking;
• Logical Link layer;
• Netlink;
• Tomoyo security module;
  (CVE-2024-26704, CVE-2023-52615, CVE-2024-26805, CVE-2023-52604,
  CVE-2024-26614, CVE-2023-52602, CVE-2024-26635, CVE-2024-26622,
  CVE-2023-52601, CVE-2024-26801)
