Linux: Out-of-bounds Read

Published Updated By the CyberSecBulletin desk

CVE-2026-46204 is a high-severity out-of-bounds read vulnerability in Linux, with a CVSS 3.1 base score of 7.1 out of 10. It can be exploited with local access to the system by an attacker with a low-privileged account, without any action from a user. The record lists versions 92724364702fd12d99f441a4af11d9c8bcd52217, 1dc005775fb5b3f86464406452b17364f85581d3, d0802a8877d730260d4af4dd4e0b6cde7e0e593f as the first without the flaw, so updating Linux to one of those releases or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.13% chance of exploitation within 30 days, which is low compared with other CVEs.

Official description

In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu/vcn4: Prevent OOB reads when parsing IB Rewrite the IB parsing to use amdgpu_ib_get_value() which handles the bounds checks.

Source: the CVE record as published by its numbering authority, via NVD and CVE.org.

The underlying weakness: Out-of-bounds Read

The product reads data past the end, or before the beginning, of the intended buffer.

How developers prevent this class of flaw

  • Use a language that provides appropriate memory abstractions.
