CVE-2024-26992 KVM: x86/pmu: Disable support for adaptive PEBS

In the Linux kernel, the following vulnerability has been resolved: KVM: x86/pmu: Disable support for adaptive PEBS Drop support for virtualizing adaptive PEBS, as KVM's implementation is architecturally broken without an obvious/easy path forward, and because exposing adaptive PEBS can leak host...

CVE-2024-26992

Summary (CVE-2024-26992): The Linux kernel KVM x86/pmu feature disabled adaptive PEBS due to architecturally broken implementation and potential leakage of host addresses (LBRs) to guests. The report enumerates several contributing issues: Bug 1, improper handling of IA32_FIXED_CTR_CTRL upper bit...

kernel: bpf: Disable preemption in bpf_perf_event_output

A flaw was found in the Linux kernel's BPF subsystem. The bpfperfeventoutput function relies on disabled preemption for nesting protection, but when called from uprobes context via bpfprogrunarraysleepable, preemption remains enabled. This allows task preemption during protected sections, leading...

kernel: bpf: Disable preemption in bpf_event_output

A race condition was found in the BPF event output mechanism. When preemption is enabled during bpfeventoutput, two tasks can access the same perfsampledata buffer concurrently, leading to data corruption and kernel crashes...

kernel: perf trace: Really free the evsel->priv area

A memory leak flaw was found in the Linux kernel's perf trace tool in the event selector cleanup logic. A local user can trigger this issue by running perf trace commands, causing the tool to free memory based on an incorrect condition check that inverts the intended logic for non-syscall...
