hw: amd: Instruction raise #VC exception at exit

A vulnerability was found in AMD SEV-SNP, where a malicious hypervisor can potentially break confidentiality and integrity of SEV-SNP on Linux guests by injecting interrupts. An attacker can inject interrupt 0x80, which is used by Linux for legacy 32-bit system calls, and arbitrarily change the...

Linux kernel 安全漏洞

Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. A security vulnerability exists in the Linux kernel that stems from a security flaw when two interrupts are raised to two CPUs at the same time...

kernel: untrusted VMM can trigger int80 syscall handling

A flaw was found in the Linux kernel. A VMM can inject external interrupts on any arbitrary vector at any time, which may allow the guest OS to be manipulated from the VMM side...

SUSE CVE-2022-48647

In the Linux kernel, the following vulnerability has been resolved: sfc: fix TX channel offset when using legacy interrupts In legacy interrupt mode the txchanneloffset was hardcoded to 1, but that's not correct if efxsepparatetxchannels is false. In that case, the offset is 0 because the tx queu...

CVE-2022-48647

CVE-2022-48647 is a Linux kernel issue in the sfc driver where legacy interrupt TX channel handling used a fixed tx_channel_offset of 1, which is incorrect when efx_sepparate_tx_channels is false. The queues reside in a single channel (index 0) with RX, so the offset should be 0; using 1 can caus...
