+
+Several vulnerabilities have been discovered in the Linux kernel that
+may lead to a privilege escalation, denial of service or information
+leaks.
+
+CVE-2021-4037
+
+ Christian Brauner reported the inode_init_owner function for the XFS
+ filesystem the Linux kernel allows local users to create files with
+ an unintended group ownership allowing attackers to escalate
+ privileges by making a plain file executable and SGID.
+
+CVE-2022-0171
+
+ Mingwei Zhang reported that a cache incoherence issue in the SEV API
+ in the KVM subsystem may result in denial of service.
+
+CVE-2022-1184
+
+ A flaw was discovered in the ext4 filesystem driver which can lead
+ to a use-after-free. A local user permitted to mount arbitrary
+ filesystems could exploit this to cause a denial of service (crash
+ or memory corruption) or possibly for privilege escalation.
+
+CVE-2022-2602
+
+ It was discovered that a race condition in the handling of
+ processing io_uring requests on a registered file and the Unix
+ socket Carbage Collection running may result in a use-after-free,
+ which may result in local privilege escalation.
+
+CVE-2022-20421
+
+ A use-after-free vulnerability was discovered in the
+ binder_inc_ref_for_node function in the Android binder driver. On
+ systems where the binder driver is loaded, a local user could
+ exploit this for privilege escalation.
+
+CVE-2022-2663
+
+ David Leadbeater reported flaws in the nf_conntrack_irc
+ connection-tracking protocol module. When this module is enabled
+ on a firewall, an external user on the same IRC network as an
+ internal user could exploit its lax parsing to open arbitrary TCP
+ ports in the firewall, to reveal their public IP address, or to
+ block their IRC connection at the firewall.
+
+CVE-2022-3061
+
+ A flaw was discovered in the i740 driver which may result in denial
+ of service.
+
+ This driver is not enabled in Debian's official kernel
+ configurations.
+
+CVE-2022-3176
+
+ A use-after-free flaw was discovered in the io_uring subsystem which
+ may result in local privilege escalation to root.
+
+CVE-2022-3303
+
+ A race condition in the snd_pcm_oss_sync function in the sound
+ subsystem in the Linux kernel due to improper locking may result in
+ denial of service.
+
+CVE-2022-39188
+
+ Jann Horn reported a race condition in the kernel's handling of
+ unmapping of certain memory ranges. When a driver created a
+ memory mapping with the VM_PFNMAP flag, which many GPU drivers do,
+ the memory mapping could be removed and freed before it was
+ flushed from the CPU TLBs. This could result in a page use-after-
+ free. A local user with access to such a device could exploit
+ this to cause a denial of service (crash or memory corruption) or
+ possibly for privilege escalation.
+
+CVE-2022-39842
+
+ An integer overflow was discovered in the pxa3xx-gcu video driver
+ which could lead to a heap out-of-bounds write.
+
+ This driver is not enabled in Debian's official kernel
+ configurations.
+
+CVE-2022-40307
+
+ A race condition was discovered in the EFI capsule-loader driver,
+ which could lead to use-after-free. A local user permitted to
+ access this device (/dev/efi_capsule_loader) could exploit this to
+ cause a denial of service (crash or memory corruption) or possibly
+ for privilege escalation. However, this device is normally only
+ accessible by the root user.
+
+CVE-2022-41674, CVE-2022-42719, CVE-2022-42720, CVE-2022-42721, CVE-2022-42722
+
+ Soenke Huster discovered several vulnerabilities in the mac80211
+ subsystem triggered by WLAN frames which may result in denial of
+ service or the execution or arbitrary code.
