CVE ID : CVE-2023-53746
Published : 8 Dec 2025, 2:15 a.m. | 32 minutes ago
Description : In the Linux kernel, the following vulnerability has been resolved: s390/vfio-ap: fix memory leak in vfio_ap device driver The device release callback function invoked to release the matrix device uses the dev_get_drvdata(device *dev) function to retrieve the pointer to the vfio_matrix_dev object in order to free its storage. The problem is, this object is not stored as drvdata with the device; since the kfree function will accept a NULL pointer, the memory for the vfio_matrix_dev object is never freed. Since the device being released is contained within the vfio_matrix_dev object, the container_of macro will be used to retrieve its pointer.
Severity: 0.0 | NA

CVE-2023-53747 - vc_screen: reload load of struct vc_data pointer in vcs_write() to avoid UAF
CVE ID : CVE-2023-53747
Published : 8 Dec 2025, 2:15 a.m. | 32 minutes ago
Description : In the Linux kernel, the following vulnerability has been resolved: vc_screen: reload load of struct vc_data pointer in vcs_write() to avoid UAF After a call to console_unlock() in vcs_write() the vc_data struct can be freed by vc_port_destruct(). Because of that, the struct vc_data pointer must be reloaded in the while loop in vcs_write() after console_lock() to avoid a UAF when vcs_size() is called. Syzkaller reported a UAF in vcs_size().
