CVE-2022-2196 A regression was discovered the KVM implementation for Intel CPUs, affecting Spectre v2 mitigation for nested virtualisation. When KVM was used as the L0 hypervisor, an L2 guest could exploit this to leak sensitive information from its L1 hypervisor. CVE-2022-3424 Zheng Wang and Zhuorao Yang reported a flaw in the SGI GRU driver which could lead to a use-after-free. On systems where this driver is used, a local user can explit this for denial of service (crash or memory corruption) or possibly for privilege escalation. This driver is not enabled in Debian's official kernel configurations. CVE-2022-3707 Zheng Wang reported a flaw in the i915 graphics driver's virtualisation (GVT-g) support that could lead to a double-free. On systems where this feature is used, a guest can exploit this for denial of service (crash or memory corruption) or possibly for privilege escalation. CVE-2022-4129 Haowei Yan reported a race condition in the L2TP protocol implementation which could lead to a null pointer dereference. A local user could exploit this for denial of service (crash). CVE-2022-4379 Xingyuan Mo reported a flaw in the NFSv4.2 inter server to server copy implementation which could lead to a use-after-free. This feature is not enabled in Debian's official kernel configurations. CVE-2023-0045 Rodrigo Branco and Rafael Correa De Ysasi reported that when a user-space task told the kernel to enable Spectre v2 mitigation for it, the mitigation was not enabled until the task was next rescheduled. This might be exploitable by a local or remote attacker to leak sensitive information from such an application. CVE-2023-0458 Jordy Zimmer and Alexandra Sandulescu found that getrlimit() and related system calls were vulnerable to speculative execution attacks such as Spectre v1. A local user could explot this to leak sensitive information from the kernel. CVE-2023-0459 Jordy Zimmer and Alexandra Sandulescu found a regression in Spectre v1 mitigation in the user-copy functions for the amd64 (64-bit PC) architecture. Where the CPUs do not implement SMAP or it is disabled, a local user could exploit this to leak sensitive information from the kernel. Other architectures may also be affected. CVE-2023-0461 "slipper" reported a flaw in the kernel's support for ULPs (Upper Layer Protocols) on top of TCP that can lead to a double-free when using kernel TLS sockets. A local user can exploit this for denial of service (crash or memory corruption) or possibly for privilege escalation. Kernel TLS is not enabled in Debian's official kernel configurations. CVE-2023-1073 Pietro Borrello reported a type confusion flaw in the HID (Human Interface Device) subsystem. An attacker able to insert and remove USB devices might be able to use this to cause a denial of service (crash or memory corruption) or possibly to run arbitrary code in the kernel.

A local user could exploit this to cause a denial of service (resource exhaustion). CVE-2023-1076 Pietro Borrello reported a type confusion flaw in the TUN/TAP network driver, which results in all TUN/TAP sockets being marked as belonging to user ID 0 (root). This may allow local users to evade local firewall rules based on user ID. CVE-2023-1077 Pietro Borrello reported a type confusion flaw in the task scheduler. A local user might be able to exploit this to cause a denial of service (crash or memory corruption) or possibly for privilege escalation. CVE-2023-1078 Pietro Borrello reported a type confusion flaw in the RDS protocol implementation. A local user could exploit this to cause a denial of service (crash or memory corruption) or possibly for privilege escalation. CVE-2023-1079 Pietro Borrello reported a race condition in the hid-asus HID driver which could lead to a use-after-free. An attacker able to insert and remove USB devices can use this to cause a denial of service (crash or memory corruption) or possibly to run arbitrary code in the kernel. CVE-2023-1118 Duoming Zhou reported a race condition in the ene_ir remote control driver that can lead to a use-after-free if the driver is unbound. It is not clear what the security impact of this is. CVE-2023-1281, CVE-2023-1829 "valis" reported two flaws in the cls_tcindex network traffic classifier which could lead to a use-after-free. A local user can exploit these for privilege escalation. This update removes cls_tcindex entirely. CVE-2023-1513 Xingyuan Mo reported an information leak in the KVM implementation for the i386 (32-bit PC) architecture. A local user could exploit this to leak sensitive information from the kernel. CVE-2023-1611 "butt3rflyh4ck" reported a race condition in the btrfs filesystem driver which can lead to a use-after-free. A local user could exploit this to cause a denial of service (crash or memory corruption) or possibly for privilege escalation. CVE-2023-1670 Zheng Wang reported a race condition in the xirc2ps_cs network driver which can lead to a use-after-free. An attacker able to insert and remove PCMCIA devices can use this to cause a denial of service (crash or memory corruption) or possibly to run arbitrary code in the kernel. CVE-2023-1855 Zheng Wang reported a race condition in the xgene-hwmon hardware monitoring driver that may lead to a use-after-free. It is not clear what the security impact of this is. CVE-2023-1859 Zheng Wang reported a race condition in the 9pnet_xen transport for the 9P filesystem on Xen, which can lead to a use-after-free. On systems where this feature is used, a backend driver in another domain can use this to cause a denial of service (crash or memory corruption) or possibly to run arbitrary code in the vulnerable domain. CVE-2023-1872 Bing-Jhong Billy Jheng reported a race condition in the io_uring subsystem that can lead to a use-after-free.
