Name of the Vulnerable Software and Affected Versions: Linux kernel affected versions not specified Description: The issue is related to the Linux kernel's bpf Berkeley Packet Filter functionality, specifically with the masking negation logic when the off reg is in the dst register. The negation...

An issue was discovered in the Linux kernel through 5.11.x. 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. Specifically for sequences of pointer arithmetic operations the pointer modification performed by the first operation is not correctly accounted for when restricting subsequent operations.
