linux - security update

Description

Several vulnerabilities have been discovered in the Linux kernel that may lead to a privilege escalation, denial of service or information leaks. * [CVE-2022-0494](https://security-tracker.debian.org/tracker/CVE-2022-0494) The scsi\_ioctl() was susceptible to an information leak only exploitable by users with CAP\_SYS\_ADMIN or CAP\_SYS\_RAWIO capabilities. * [CVE-2022-0854](https://security-tracker.debian.org/tracker/CVE-2022-0854) Ali Haider discovered a potential information leak in the DMA subsystem. On systems where the swiotlb feature is needed, this might allow a local user to read sensitive information. * [CVE-2022-1012](https://security-tracker.debian.org/tracker/CVE-2022-1012) The randomisation when calculating port offsets in the IP implementation was enhanced. * [CVE-2022-1729](https://security-tracker.debian.org/tracker/CVE-2022-1729) Norbert Slusarek discovered a race condition in the perf subsystem which could result in local privilege escalation to root. The default settings in Debian prevent exploitation unless more permissive settings have been applied in the kernel.perf\_event\_paranoid sysctl. * [CVE-2022-1786](https://security-tracker.debian.org/tracker/CVE-2022-1786) Kyle Zeng discovered a use-after-free in the io\_uring subsystem which way result in local privilege escalation to root. * [CVE-2022-1789](https://security-tracker.debian.org/tracker/CVE-2022-1789) / [CVE-2022-1852](https://security-tracker.debian.org/tracker/CVE-2022-1852) Yongkang Jia, Gaoning Pan and Qiuhao Li discovered two NULL pointer dereferences in KVM's CPU instruction handling, resulting in denial of service. * [CVE-2022-32250](https://security-tracker.debian.org/tracker/CVE-2022-32250) Aaron Adams discovered a use-after-free in Netfilter which may result in local privilege escalation to root. * [CVE-2022-1974](https://security-tracker.debian.org/tracker/CVE-2022-1974) / [CVE-2022-1975](https://security-tracker.debian.org/tracker/CVE-2022-1975) Duoming Zhou discovered that the NFC netlink interface was suspectible to denial of service. * [CVE-2022-2078](https://security-tracker.debian.org/tracker/CVE-2022-2078) Ziming Zhang discovered an out-of-bound write in Netfilter which may result in local privilege escalation to root. * [CVE-2022-21499](https://security-tracker.debian.org/tracker/CVE-2022-21499) It was discovered that the kernel debugger could be used to bypass UEFI Secure Boot restrictions. * [CVE-2022-28893](https://security-tracker.debian.org/tracker/CVE-2022-28893) Felix Fu discovered a use-after-free in the implementation of the Remote Procedure Call (SunRPC) protocol, which could result in denial of service or an information leak. For the stable distribution (bullseye), these problems have been fixed in version 5.10.120-1. We recommend that you upgrade your linux packages.
