**CentOS Errata and Security Advisory** CESA-2022:5937
The kernel packages contain the Linux kernel, the core of any Linux operating system.
Security Fix(es):
* Incomplete cleanup of multi-core shared buffers (aka SBDR) (CVE-2022-21123)
* Incomplete cleanup of microarchitectural fill buffers (aka SBDS) (CVE-2022-21125)
* Incomplete cleanup in specific special register write operations (aka DRPW) (CVE-2022-21166)
For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.
Bug Fix(es):
* SolarFlare sfc spurious TX completion (BZ#1793280)
* Page allocation failure on cryptsetup open (BZ#2072970)
* The kernel-rt crashes where one task is indefinitely looping in __start_cfs_bandwidth() with the cfs_b->lock spinlock being held (BZ#2077346)
* While using PTimekeeper the qede driver produces excessive log messages (BZ#2080646)
* The kernel crashes due to a GPF happens in mutex_spin_on_owner(). The known RDMA/cma bug that was introduced with a patch from upstream commit 722c7b2bfead is the possible cause. (BZ#2085425)
* Running LTP testcase creat09 fails showing related to 'cve-2018-13405' (BZ#2089360)
* Crash when releasing inode which was on unmouted superblock (BZ#2096884)

(CVE-2022-23825)\n\n - x86 pv: Race condition in typeref acquisition Xen maintains a type reference count for pages, in addition to a regular reference count. This scheme is used to maintain invariants required for Xen's safety, e.g.\n PV guests may not have direct writeable access to pagetables; updates need auditing by Xen. Unfortunately, the logic for acquiring a type reference has a race condition, whereby a safely TLB flush is issued too early and creates a window where the guest can re-establish the read/write mapping before writeability is prohibited. (CVE-2022-26362)\n\n - x86 pv: Insufficient care with non-coherent mappings T[his CNA information record relates to multiple CVEs; the text explains which aspects/vulnerabilities correspond to which CVE.] Xen maintains a type reference count for pages, in addition to a regular reference count. This scheme is used to maintain invariants required for Xen's safety, e.g. PV guests may not have direct writeable access to pagetables;\n updates need auditing by Xen. Unfortunately, Xen's safety logic doesn't account for CPU-induced cache non- coherency; cases where the CPU can cause the content of the cache to be different to the content in main memory. In such cases, Xen's safety logic can incorrectly conclude that the contents of a page is safe.\n (CVE-2022-26363, CVE-2022-26364)\n\n - Mis-trained branch predictions for return instructions may allow arbitrary speculative code execution under certain microarchitecture-dependent conditions. (CVE-2022-29900)\n\n - insufficient TLB flush for x86 PV guests in shadow mode For migration as well as to work around kernels unaware of L1TF (see XSA-273), PV guests may be run in shadow paging mode. To address XSA-401, code was moved inside a function in Xen. This code movement missed a variable changing meaning / value between old and new code positions. The now wrong use of the variable did lead to a wrong TLB flush condition, omitting flushes where such are necessary.
