Description

mnl has segmentation fault and invalid memory read in mnl::cb_run

The function mnl::cb_run is marked as safe but exhibits unsound behavior when processing malformed Netlink message buffers.

Passing a crafted byte slice to mnl::cb_run can trigger memory violations. The function does not sufficiently validate the input buffer structure before processing, leading to out-of-bounds reads.

This vulnerability allows an attacker to cause a Denial of Service (segmentation fault) or potentially read unmapped memory by providing a malformed Netlink message.

How this vulnerability can be exploited

This issue can be reached with local access to the system, attack complexity is low, an attacker needs no privileges on the target. No user interaction is required. Rated impact: confidentiality none, integrity none, availability low.

Weakness class

GHSA-585q-cm62-757j is classified as CWE-125: Out-of-bounds Read. The code reads past the limits of a buffer, exposing adjacent memory contents or crashing the process.
