CVE-2024-56621

CVE-2024-56621 affects the Linux kernel SCSI/UFS subsystem. The root cause was that RTC work was cancelled only during __ufshcd_wl_suspend(), not when ufshcd is removed, allowing RTC work to run on removed internal ufshcd structures and potentially dereference NULL. The fix cancels RTC work durin...

CVE-2024-56591

CVE-2024-56591 affects the Linux kernel Bluetooth subsystem, specifically hci_conn. The issue stems from using cancel_delayed_work_sync, which cancels ongoing work but may allow new work and can lead to the object being freed in hci_conn. The vendor advisories describe the root cause as related t...
