CVE-2025-21773: NULL Pointer Dereference

In the Linux kernel, the following vulnerability has been resolved: can: etases58x: fix potential NULL pointer dereference on udev-serial The driver assumed that es58xdev-udev-serial could never be NULL. While this is true on commercially available devices, an attacker could spoof the device...

USN-7294-1 linux-azure, linux-azure-5.4, linux-bluefield, linux-gcp, linux-gcp-5.4, linux-ibm-5.4 vulnerabilities

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: - ARM64 architecture; - Block layer subsystem; - ACPI drivers; - Drivers core; - ATA over ethernet AOE driver; - TPM...

USN-7295-1 linux-xilinx-zynqmp vulnerabilities

Ye Zhang and Nicolas Wu discovered that the iouring subsystem in the Linux kernel did not properly handle locking for rings with IOPOLL, leading to a double-free vulnerability. A local attacker could use this to cause a denial of service system crash or possibly execute arbitrary code...

USN-7291-1 linux-gcp, linux-gcp-5.15, linux-gke vulnerabilities

This update corrects flaws in the following subsystems: - ARM64 architecture; - x86 architecture; - Block layer subsystem; - ACPI drivers; - GPU drivers; - HID subsystem; -...

DEBIAN-CVE-2022-49713

In the Linux kernel, the following vulnerability has been resolved: usb: dwc2: Fix memory leak in dwc2hcdinit usbcreatehcd will alloc memory for hcd, and we should call usbputhcd to free it when platformgetresource fails to prevent memory leak. goto error2 label instead error1 to fix this...

CVE-2022-49613

In the Linux kernel, the following vulnerability has been resolved: serial: 8250: Fix PM usagecount for console handover When console is enabled, univ8250consolesetup calls serial8250consolesetup before .dev is set to uartport.
