CVE-2021-29649
An issue was discovered in the Linux kernel before 5.11.11. The user mode driver UMD has a copyprocess memory leak, related to a lack of cleanup steps in kernel/usermodedriver.c and kernel/bpf/preload/bpfpreloadkern.c, aka CID-f60a85cad677...
New Bugs Could Let Hackers Bypass Spectre Attack Mitigations On Linux Systems
Cybersecurity researchers on Monday disclosed two new vulnerabilities in Linux-based operating systems that, if successfully exploited, could let attackers circumvent mitigations for speculative attacks such as Spectre and obtain sensitive information from kernel memory. Discovered by Piotr Krysi...
