It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-74448 in the wild and no public exploit code.\n\nAffected product: Linux. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-74448/ (Markdown: https://insights.sbomify.com/CVE-2026-74448/index.md)","id":"CVE-2026-74448","markdown":"https://insights.sbomify.com/CVE-2026-74448/index.md","name":"CVE-2026-74448","record":{"aliases":["AZL-96450","BELL-CVE-2026-74448","DEBIAN-CVE-2026-74448","GHSA-8x3r-qg94-9qh5","UBUNTU-CVE-2026-74448"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"Linux kernel driver","requires_auth":"low_privilege","summary":"A local attacker can exhaust GPU queue slots by triggering a memory allocation failure, causing denial of service for subsequent queue creations.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\ndrm/amdkfd: fix QID bit leak in pqm_create_queue()\n\nWhen MES is enabled and amdgpu_amdkfd_alloc_kernel_mem() fails during\nthe first queue creation for a process, pqm_create_queue() returns\nearly via 'return retval' without going through the err_create_queue\ncleanup label.\n\nThis means clear_bit(*qid, pqm-\u003equeue_slot_bitmap) is never called,\nleaving the reserved QID bit permanently set in queue_slot_bitmap.\nOver time this leaks QID slots, potentially exhausting all available\nqueue slots.\n\nFix this by replacing 'return retval' with 'goto err_allocate_pqn'\nso that clear_bit() is always called on the error path without\ntouching the uninitialized pqn pointer.\n\nAILIKFD-813\n\n(cherry picked from commit a107f74c38edbb80d6ab64dcaeeb292c14e9779f)","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"drm/amdkfd: fix QID bit leak in pqm_create_queue()","id":"CVE-2026-74448","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2026"},"n_packages":0,"n_references":5,"next":{"headline":"drm/amd/display: Fix divide-by-zero in calculate_mcache_setting on zero viewport","id":"CVE-2026-74449"},"packages":[],"prev":{"headline":"drm/amdkfd: fix uint32_t overflow in EOP ring buffer size alignment","id":"CVE-2026-74447"},"products":["Linux"],"published":"2026-08-15","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-08-18","vendors":["Linux"]},"summary":"A local attacker can exhaust GPU queue slots by triggering a memory allocation failure, causing denial of service for subsequent queue creations.","url":"https://insights.sbomify.com/CVE-2026-74448/"}
