This kernel update is based on upstream 5.15.28 and fixes at least the following security issues:

Non-transparent sharing of branch predictor selectors between contexts in some Intel(R) Processors may allow an authorized user to potentially enable information disclosure via local access (CVE-2022-0001).

Non-transparent sharing of branch predictor within a context in some Intel(R) Processors may allow an authorized user to potentially enable information disclosure via local access (CVE-2022-0002).

A memory leak flaw was found in the Linux kernel’s ICMPv6 networking protocol, in the way a user generated malicious ICMPv6 packets. This flaw allows a remote user to crash the system (CVE-2022-0742).

Several Linux PV device frontends are using the grant table interfaces for removing access rights of the backends in ways being subject to race conditions, resulting in potential data leaks, data corruption by malicious backends, and denial of service triggered by malicious backends:

blkfront, netfront, scsifront and the gntalloc driver are testing whether a grant reference is still in use. If this is not the case, they assume that a following removal of the granted access will always succeed, which is not true in case the backend has mapped the granted page between those two operations. As a result the backend can keep access to the memory page of the guest no matter how the page will be used after the frontend I/O has finished. The xenbus driver has a similar problem, as it doesn't check the success of removing the granted access of a shared ring buffer (blkfront: CVE-2022-23036, netfront: CVE-2022-23037, scsifront: CVE-2022-23038, gntalloc: CVE-2022-23039, xenbus: CVE-2022-23040)

blkfront, netfront, scsifront, usbfront, dmabuf, xenbus, 9p, kbdfront, and pvcalls are using a functionality to delay freeing a grant reference until it is no longer in use, but the freeing of the related data page is not synchronized with dropping the granted access. As a result the backend can keep access to the memory page even after it has been freed and then re-used for a different purpose (CVE-2022-23041).

netfront will fail a BUG_ON() assertion if it fails to revoke access in the rx path. This will result in a Denial of Service (DoS) situation of the guest which can be triggered by the backend (CVE-2022-23042).

Certain Arm Cortex and Neoverse processors through 2022-03-08 do not properly restrict cache speculation, aka Spectre-BHB. An attacker can leverage the shared branch history in the Branch History Buffer (BHB) to influence mispredicted branches. Then, cache allocation can allow the attacker to obtain sensitive information (CVE-2022-23960).

It was found that the default LFENCE-based Spectre v2 mitigation on AMD cpus is insufficient to mitigate such attacks. Becuse of that, the code have been switched to use generic retpolines on AMD cpus by default.

The SUSE Linux Enterprise 15 SP1 kernel was updated to receive various security and bugfixes.

Transient execution side-channel attacks attacking the Branch History Buffer (BHB), named 'Branch Target Injection' and 'Intra-Mode Branch History Injection' are now mitigated.

The following security bugs were fixed:

The SUSE Linux Enterprise 11 SP4 kernel was updated to receive various security and bugfixes.

Transient execution side-channel attacks attacking the Branch History Buffer (BHB), named 'Branch Target Injection' and 'Intra-Mode Branch History Injection' are now mitigated.

The following security bugs were fixed:

• CVE-2022-0001: Fixed Branch History Injection vulnerability (bsc#1191580).

• CVE-2022-0617: Fixed a null pointer dereference in UDF file system functionality. A local user could crash the system by triggering udf_file_write_iter() via a malicious UDF image. (bsc#1196079)
• CVE-2022-0492: Fixed a privilege escalation related to cgroups v1 release_agent feature, which allowed bypassing namespace isolation unexpectedly (bsc#1195543).
• CVE-2021-45095: Fixed refcount leak in pep_sock_accept in net/phonet/pep.c (bsc#1193867).
• CVE-2021-4155: Fixed a data leak flaw that allows a local attacker to leak data on the XFS filesystem (bsc#1194272).
• CVE-2020-27820: Fixed a vulnerability where a use-after-frees in nouveau's postclose() handler could happen if removing device (bsc#1179599).
• CVE-2019-0136: Fixed an insufficient access control which allow an unauthenticated user to execute a denial of service (bsc#1193157).
• CVE-2021-3753: Fixed race out-of-bounds in virtual terminal handling (bsc#1190025).

The following non-security bugs were fixed:

• kprobes: Limit max data_size of the kretprobe instances (bsc#1193669).
• md: check the return of mddev_find() (bsc#1195109).

Nick Gregory discovered that the Linux kernel incorrectly handled network offload functionality. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. (CVE-2022-25636)

Enrico Barberis, Pietro Frigo, Marius Muench, Herbert Bos, and Cristiano Giuffrida discovered that hardware mitigations added by ARM to their processors to address Spectre-BTI were insufficient. A local attacker could potentially use this to expose sensitive information. (CVE-2022-23960)

Max Kellermann discovered that the Linux kernel incorrectly handled Unix pipes. A local attacker could potentially use this to modify any file that could be opened for reading. (CVE-2022-0847)

Enrico Barberis, Pietro Frigo, Marius Muench, Herbert Bos, and Cristiano Giuffrida discovered that hardware mitigations added by Intel to their processors to address Spectre-BTI were insufficient. A local attacker could potentially use this to expose sensitive information. (CVE-2022-0001, CVE-2022-0002)
