CVE-2024-49915: drm/amd/display: Add NULL check for clk_mgr in dcn32_init_hw
Noroxi assessment
Priority: Monitor (action score 22/100)
- The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
- Probability of exploitation in the next 30 days: 0.23% (FIRST EPSS).
- Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
- Fixed version: Linux Linux 0d94d9cbd9fec7344d230c4f7b781826f7799c60, 7d1854c86d02cea8f8a0c0ca05f4ab14292baf3d, c395fd47d1565bd67671f45cca281b3acc2c31ef; azl3 kernel 6.6.64.2-9 on Azure Linux 3.0 6.6.64.2-9; azl3 kernel 6.6.92.2-1 on Azure Linux 3.0 6.6.64.2-9.
Low priority for now. Upgrade to Linux Linux 0d94d9cbd9fec7344d230c4f7b781826f7799c60, 7d1854c86d02cea8f8a0c0ca05f4ab14292baf3d, c395fd47d1565bd67671f45cca281b3acc2c31ef; azl3 kernel 6.6.64.2-9 on Azure Linux 3.0 6.6.64.2-9; azl3 kernel 6.6.92.2-1 on Azure Linux 3.0 6.6.64.2-9 or later.

Primary sources: NVD · CVE.org · FIRST EPSS
In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Add NULL check for clk_mgr in dcn32_init_hw This commit addresses a potential null pointer dereference issue in the `dcn32_init_hw` function. The issue could occur when `dc->clk_mgr` is null. The fix adds a check to ensure `dc->clk_mgr` is not null before accessing its functions. This prevents a potential null pointer dereference. Reported by smatch: drivers/gpu/drm/amd/amdgpu/../display/dc/hwss/dcn32/dcn32_hwseq.c:961 dcn32_init_hw() error: we previously assumed 'dc->clk_mgr' could be null (see line 782)
