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...

An issue was discovered in the Linux kernel before 5.11.8. kernel/bpf/verifier.c performs undesirable out-of-bounds speculation on pointer arithmetic leading to side-channel attacks that defeat Spectre mitigations and obtain sensitive information from kernel memory aka CID-f232326f6966. This affects pointer types that do not define a ptr_limit.
