Piotr Krysiuk discovered that the BPF subsystem in the Linux kernel did not properly compute a speculative execution limit on pointer arithmetic in some situations. A local attacker could use this to expose sensitive information kernel memory. CVE-2020-27171 Piotr Krysiuk discovered that the BPF...

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.

De4dCr0w of 360 Alpha Lab discovered that the BPF verifier in the Linux kernel did not properly handle mod32 destination register truncation when the source register was known to be 0. A local attacker could use this to expose sensitive information kernel memory or possibly execute arbitrary code...

Updated kernel packages fix security issues

This kernel update is based on upstream 5.10.25 and fixes at least the following security issues: Unprivileged BPF programs running on affected systems can bypass the protection and execute speculatively out-of-bounds loads from any location within the kernel memory. This can be abused to extract...

CVE-2018-12130

A flaw was found in the implementation of the "fill buffer", a mechanism used by modern CPUs when a cache-miss is made on L1 CPU cache. If an attacker can generate a load operation that would create a page fault, the execution will continue speculatively with incorrect data from the fill buffer...

DEBIAN-CVE-2020-27171

An issue was discovered in the Linux kernel before 5.11.8. kernel/bpf/verifier.c has an off-by-one error with a resultant integer underflow affecting out-of-bounds speculation on pointer arithmetic, leading to side-channel attacks that defeat Spectre mitigations and obtain sensitive information...

CVE-2018-3620
