https://notcve.org/view.php?id=CVE-2024-49902
In the Linux kernel, the following vulnerability has been resolved: jfs: check if leafidx greater than num leaves per dmap tree syzbot report a out of bounds in dbSplit, it because dmt_leafidx greater than num leaves per dmap tree, add a checking for dmt_leafidx in dbFindLeaf. Shaggy: Modified sanity check to apply to control pages as well as leaf pages. • https://git.kernel.org/stable/c/2451e5917c56be45d4add786e2a059dd9c2c37c4 https://git.kernel.org/stable/c/25d2a3ff02f22e215ce53355619df10cc5faa7ab https://git.kernel.org/stable/c/058aa89b3318be3d66a103ba7c68d717561e1dc6 https://git.kernel.org/stable/c/7fff9a9f866e99931cf6fa260288e55d01626582 https://git.kernel.org/stable/c/cb0eb10558802764f07de1dc439c4609e27cb4f0 https://git.kernel.org/stable/c/4a7bf6a01fb441009a6698179a739957efd88e38 https://git.kernel.org/stable/c/d64ff0d2306713ff084d4b09f84ed1a8c75ecc32 •
CVSS: -EPSS: 0%CPEs: 4EXPL: 0CVE-2024-49901 – drm/msm/adreno: Assign msm_gpu->pdev earlier to avoid nullptrs
https://notcve.org/view.php?id=CVE-2024-49901
In the Linux kernel, the following vulnerability has been resolved: drm/msm/adreno: Assign msm_gpu->pdev earlier to avoid nullptrs There are some cases, such as the one uncovered by Commit 46d4efcccc68 ("drm/msm/a6xx: Avoid a nullptr dereference when speedbin setting fails") where msm_gpu_cleanup() : platform_set_drvdata(gpu->pdev, NULL); is called on gpu->pdev == NULL, as the GPU device has not been fully initialized yet. Turns out that there's more than just the aforementioned path that causes this to happen (e.g. the case when there's speedbin data in the catalog, but opp-supported-hw is missing in DT). Assigning msm_gpu->pdev earlier seems like the least painful solution to this, therefore do so.
