🛡️ CVE-2024-46821 on Ubuntu — linux
Description
In the Linux kernel, the following vulnerability has been resolved: drm/amd/pm: Fix negative array index read Avoid using the negative values for clk_idex as an index into an array pptable->DpmDescriptor. V2: fix clk_index return check (Tim Huang)
Distribution advisory
This page covers CVE-2024-46821 as tracked by Ubuntu, for the package linux. The fix is available in version 6.8.0-50.51; earlier versions remain affected.
How this vulnerability can be exploited
This issue can be reached with local access to the system, attack complexity is low, an attacker needs low-level privileges on the target. No user interaction is required. The scope is unchanged, so the impact stays within the vulnerable component. Rated impact: confidentiality high, integrity high, availability high.
CVSS metrics in full
The score comes from this vector: CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
- Attack vector: Local — a local account, shell or session on the host is needed.
- Attack complexity: Low — the attack works reliably, with no preparation.
- Privileges required: Low — an ordinary user account is enough.
- User interaction: None — nobody has to be tricked into anything.
- Scope: Unchanged — the damage stays inside the vulnerable component.
- Confidentiality impact: High — total loss, or loss the attacker controls.
- Integrity impact: High — total loss, or loss the attacker controls.
- Availability impact: High — total loss, or loss the attacker controls.
Weakness class
UBUNTU-CVE-2024-46821 is classified as CWE-129: Improper Validation of Array Index. An index derived from input is used without a range check, so the access lands outside the array.
