CVE-2022-48804

In the Linux kernel, the following vulnerability has been resolved: vtioctl: fix arrayindexnospec in vtsetactivate arrayindexnospec ensures that an out-of-bounds value is set to zero on the transient path. Decreasing the value by one afterwards causes a transient integer underflow. vsa.console...

CVE-2022-48804

CVE-2022-48804 is resolved in the Linux kernel’s vt_ioctl/vt_setactivate path. The vulnerability stems from an array_index_nospec handling that could allow a transient integer underflow when an out-of-bounds value is decremented after zero, specifically affecting vsa.console handling. The descrip...

Poor Rowhammer Fixes On DDR4 DRAM Chips Re-Enable Bit Flipping Attacks

Remember rowhammer vulnerability? A critical issue affecting modern DRAM dynamic random access memory chips that could allow attackers to obtain higher kernel privileges on a targeted system by repeatedly accessing memory cells and induce bit flips. To mitigate Rowhammer vulnerability on the late...

Intel ZombieLoad Side-Channel Attack: 10 Takeaways

Intel on Tuesday revealed a new class of speculative execution vulnerabilities, dubbed Microarchitectural Data Sampling MDS, which impact all its modern CPUs. The flaws all ultimately depend on different ways of executing side channel attacks to siphon data from impacted systems – and result in...

A Simple JavaScript Exploit Bypasses ASLR Protection On 22 CPU Architectures

Security researchers have discovered a chip flaw that could nullify hacking protections for millions of devices regardless of their operating system or application running on them, and the worse — the flaw can not be entirely fixed with any mere software update. The vulnerability resides in the w...
