CVE-2024-41068 — s390/sclp: Fix sclp_init() cleanup on failure

Affected: Linux

In the Linux kernel, the following vulnerability has been resolved:

s390/sclp: Fix sclp_init() cleanup on failure

If sclp_init() fails it only partially cleans up: if there are multiple failing calls to sclp_init() sclp_state_change_event will be added several times to sclp_reg_list, which results in the following warning:

------------[ cut here ]------------ list_add double add: new=000003ffe1598c10, prev=000003ffe1598bf0, next=000003ffe1598c10.

Fix this by removing sclp_state_change_event from sclp_reg_list when sclp_init() fails.

Ziming Zhang discovered that the VMware Virtual GPU DRM driver in the Linux kernel contained an integer overflow vulnerability. A local attacker could use this to cause a denial of service (system crash). (CVE-2022-36402)

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; - PowerPC architecture; - User-Mode Linux (UML); - x86 architecture; - Block layer subsystem; - Cryptographic API; - Android drivers; - Serial ATA and Parallel ATA drivers; - ATM drivers; - Drivers core; - CPU frequency scaling framework; - Device frequency scaling framework; - GPU drivers; - HID subsystem; - Hardware monitoring drivers; - InfiniBand drivers; - Input Device core drivers; - IOMMU subsystem; - IRQ chip drivers; - ISDN/mISDN subsystem; - LED subsystem; - Multiple devices driver; - Media drivers; - EEPROM drivers; - VMware VMCI Driver; - MMC subsystem; - Network drivers; - Near Field Communication (NFC) drivers; - NVME drivers; - Device tree and open firmware driver; - Parport drivers; - PCI subsystem; - Pin controllers subsystem; - Remote Processor subsystem; - S/390 drivers; - SCSI drivers; - QCOM SoC drivers; - Direct Digital Synthesis drivers; - TTY drivers; - Userspace I/O drivers; - DesignWare USB3 driver; - USB subsystem; - BTRFS file system; - File sy…
