It was discovered that a race condition existed in the Bluetooth subsystem
in the Linux kernel, leading to a null pointer dereference vulnerability. A
privileged local attacker could use this to possibly cause a denial of
service (system crash). (CVE-2024-24860)

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:
 - SuperH RISC architecture,
 - User-Mode Linux (UML),
 - GPU drivers,
 - HID subsystem,
 - MMC subsystem,
 - Network drivers,
 - PHY drivers,
 - SCSI drivers,
 - USB subsystem,
 - Xen hypervisor drivers,
 - GFS2 file system,
 - Memory management,
 - Bluetooth subsystem,
 - IPv4 networking,
 - IPv6 networking,
 - NFC subsystem,
 - HD-audio driver,
 - ALSA SH drivers,
