An update is available for kernel-rt.
This update affects Rocky Linux 8.
A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE list
The kernel-rt packages provide the Real Time Linux Kernel, which enables fine-tuning for systems with extremely high determinism requirements.
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):
* The latest Rocky Linux 8.6.z3 kernel changes need to be merged into the RT source tree to keep source parity between the two kernels. (BZ#2111112)

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.

By executing a specially-crafted program, an attacker\n could exploit this vulnerability to execute arbitrary code or cause a denial of service condition on the\n system.

This flaw allows a local\n user to crash or potentially escalate their privileges on the system. (CVE-2022-1679)\n\n - With shadow paging enabled, the INVPCID instruction results in a call to kvm_mmu_invpcid_gva. If INVPCID\n is executed with CR0.PG=0, the invlpg callback is not set and the result is a NULL pointer dereference.\n (CVE-2022-1789)\n\n - A NULL pointer dereference flaw was found in the Linux kernel's KVM module, which can lead to a denial of\n service in the x86_emulate_insn in arch/x86/kvm/emulate.c. This flaw occurs while executing an illegal\n instruction in guest in the Intel CPU. (CVE-2022-1852)\n\n - A vulnerability was found in the Linux kernel's nft_set_desc_concat_parse() function .This flaw allows an\n attacker to trigger a buffer overflow via nft_set_desc_concat_parse() , causing a denial of service and\n possibly to run code. (CVE-2022-2078)\n\n - Incomplete cleanup of multi-core shared buffers for some Intel(R) Processors may allow an authenticated\n user to potentially enable information disclosure via local access.
