Important: kernel

Issue Overview: A flaw was found in hw. Aliases in the branch predictor may cause some AMD processors to predict the wrong branch type, potentially leading to information disclosure. CVE-2022-23825 Non-transparent sharing of return predictor targets between contexts in some IntelR Processors may...

SUSE CVE-2023-0045

The current implementation of the prctl syscall does not issue an IBPB immediately during the syscall. The ibprctlset function updates the Thread Information Flags TIFs for the task and updates the SPECCTRL MSR on the function speculationctrlupdate, but the IBPB is only issued on the next schedul...

AMD ID: AMD-SB-7015 Potential Impact: N/A Severity: N/A Summary Researchers from the University of California San Diego have shared with AMD a paper titled “Pathfinder: High-Resolution Control-Flow Attacks Exploiting the Conditional Branch Predictor” that explores methods for forcing a branch...

F5 Networks BIG-IP : Side-channel processor vulnerability (K35135935)

The version of F5 Networks BIG-IP installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the K35135935 advisory. - Systems with microprocessors utilizing speculative execution may allow unauthorized disclosure of information to an...

x86/AMD: Speculative Return Stack Overflow

ISSUE DESCRIPTION Researchers from ETH Zurich have extended their prior research XSA-422, Branch Type Confusion, a.k.a Retbleed and have discovered INCEPTION, also know as RAS Return Address Stack Poisoning, and Speculative Return Stack Overflow. The RAS is updated when a CALL instruction is...

kernel: KVM: nVMX: missing IBPB when exiting from nested guest can lead to Spectre v2 attacks

A flaw was found in the KVM's Intel nested virtualization feature nVMX. Since L1 and L2 shared branch prediction modes guest-user and guest-kernel, KVM did not protect indirect branches in L1 from steering by a malicious agent in L2. This could allow a malicious nested guest to carry out Spectre ...
