CVE-2022-49124: Undefined Security Weakness
In the Linux kernel, the following vulnerability has been resolved: x86/mce: Work around an erratum on fast string copy instructions A rare kernel panic scenario can happen when the following conditions are met due to an erratum on fast string copy instructions: 1 An uncorrected error. 2 That err...
x86/Intel: Gather Data Sampling
ISSUE DESCRIPTION A researcher has discovered Gather Data Sampling, a transient execution side-channel whereby the AVX GATHER instructions can forward the content of stale vector registers to dependent instructions. The physical register file is a structure competitively shared between sibling...
SUSE CVE-2014-8867
The acceleration support for the "REP MOVS" instruction in Xen 4.4.x, 3.2.x, and earlier lacks properly bounds checking for memory mapped I/O MMIO emulated in the hypervisor, which allows local HVM guests to cause a denial of service host crash via unspecified vectors...
Denial Of Service (DoS)
The kernel packages contain the Linux kernel, the core of any Linux operating system. It was found that the Linux kernel's Infiniband subsystem did not properly sanitize input parameters while registering memory regions from user space via the uverbs API. A local user with access to a...
