CVE-2022-39188

An issue was discovered in include/asm-generic/tlb.h in the Linux kernel before 5.19. Because of a race condition unmapmappingrange versus munmap, a device driver can free a page while it still has stale TLB entries. This only occurs in situations with VMPFNMAP VMAs...

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 versions of Linux kernel prior to 5.18.17, which stems from the x86 architecture-based KVM subsystem due to a TLB refresh operation being...

DEBIAN-CVE-2022-33745

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 / val...
