Package : linux Version : 4.19.260-1 CVE ID : CVE-2021-4159 CVE-2021-33655 CVE-2021-33656 CVE-2022-1462 CVE-2022-1679 CVE-2022-2153 CVE-2022-2318 CVE-2022-2586 CVE-2022-2588 CVE-2022-2663 CVE-2022-3028 CVE-2022-26365 CVE-2022-26373 CVE-2022-33740 CVE-2022-33741 CVE-2022-33742 CVE-2022-33744 CVE-2022-36879 CVE-2022-36946 CVE-2022-39188 CVE-2022-39842 CVE-2022-40307 Debian Bug : 1018752

Several vulnerabilities have been discovered in the Linux kernel that may lead to privilege escalation, denial of service or information leaks.

CVE-2021-4159

A flaw was found in the eBPF verifier which could lead to an out-of-bounds read. If unprivileged use of eBPF is enabled, this could leak sensitive information. This was already disabled by default, which would fully mitigate the vulnerability.

CVE-2021-33655

A user with access to a framebuffer console device could cause a memory out-of-bounds write via the FBIOPUT_VSCREENINFO ioctl.

CVE-2021-33656

A user with access to a framebuffer console device could cause a memory out-of-bounds write via some font setting ioctls. These obsolete ioctls have been removed.

CVE-2022-1462

reported a race condition in the pty (pseudo-terminal) subsystem that can lead to a slab out-of-bounds write. A local user could exploit this to cause a denial of service (crash or memory corruption) or possibly for privilege escalation.

CVE-2022-1679

The syzbot tool found a race condition in the ath9k_htc driver which can lead to a use-after-free. This might be exploitable to cause a denial service (crash or memory corruption) or possibly for privilege escalation.

CVE-2022-2153

kangel reported a flaw in the KVM implementation for x86 processors which could lead to a null pointer dereference. A local user permitted to access /dev/kvm could exploit this to cause a denial of service (crash).

CVE-2022-2318

A use-after-free in the Amateur Radio X.25 PLP (Rose) support may result in denial of service.

CVE-2022-2586

A use-after-free in the Netfilter subsystem may result in local privilege escalation for a user with the CAP_NET_ADMIN capability in any user or network namespace.

CVE-2022-2588

Zhenpeng Lin discovered a use-after-free flaw in the cls_route filter implementation which may result in local privilege escalation for a user with the CAP_NET_ADMIN capability in any user or network namespace.

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-2022-3028

Abhishek Shah reported a race condition in the AF_KEY subsystem, which could lead to an out-of-bounds write or read. A local user could exploit this to cause a denial of service (crash or memory corruption), to obtain sensitive information, or possibly for privilege escalation.

CVE-2022-26365, CVE-2022-33740, CVE-2022-33741, CVE-2022-33742

Roger Pau Monne discovered that Xen block and network PV device frontends don't zero out memory regions before sharing them with the backend, which may result in information disclosure.
Additionally it was discovered that the granularity of the grant table doesn't permit sharing less than a 4k page, which may also result in information disclosure.

CVE-2022-26373

It was discovered that on certain processors with Intel's Enhanced Indirect Branch Restricted Speculation (eIBRS) capabilities there are exceptions to the documented properties in some situations, which may result in information disclosure.

Intel's explanation of the issue can be found at https://www.intel.com/content/www/us/en/developer/articles/technical/software-security- guidance/advisory-guidance/post-barrier-return-stack-buffer-predictions.html

CVE-2022-33744

Oleksandr Tyshchenko discovered that ARM Xen guests can cause a denial of service to the Dom0 via paravirtual devices.

CVE-2022-36879

A flaw was discovered in xfrm_expand_policies in the xfrm subsystem which can cause a reference count to be dropped twice.

CVE-2022-36946

Domingo Dirutigliano and Nicola Guerrera reported a memory corruption flaw in the Netfilter subsystem which 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.

For Debian 10 buster, these problems have been fixed in version 4.19.260-1.

We recommend that you upgrade your linux packages.
