CVE-2024-36897 – drm/amd/display: Atom Integrated System Info v2_2 for DCN35
https://notcve.org/view.php?id=CVE-2024-36897
30 May 2024 — In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Atom Integrated System Info v2_2 for DCN35 New request from KMD/VBIOS in order to support new UMA carveout model. This fixes a null dereference from accessing Ctx->dc_bios->integrated_info while it was NULL. DAL parses through the BIOS and extracts the necessary integrated_info but was missing a case for the new BIOS version 2.3.

CVE-2024-36896 – USB: core: Fix access violation during port device removal

30 May 2024 — In the Linux kernel, the following vulnerability has been resolved: USB: core: Fix access violation during port device removal Testing with KASAN and syzkaller revealed a bug in port.c:disable_store(): usb_hub_to_struct_hub() can return NULL if the hub that the port belongs to is concurrently removed, but the function does not check for this possibility before dereferencing the returned value. It turns out that the first dereference is unnecessary, since hub->intfdev is the parent of the port device, so it ... • https://git.kernel.org/stable/c/f061f43d7418cb62b8d073e221ec75d3f5b89e17 • CWE-170: Improper Null Termination CWE-476: NULL Pointer Dereference •

30 May 2024 — In the Linux kernel, the following vulnerability has been resolved: maple_tree: fix mas_empty_area_rev() null pointer dereference Currently the code calls mas_start() followed by mas_data_end() if the maple state is MA_START, but mas_start() may return with the maple state node == NULL. This will lead to a null pointer dereference when checking information in the NULL node, which is done in mas_data_end(). Avoid setting the offset if there is no node by waiting until after the maple state is checked for an ... • https://git.kernel.org/stable/c/54a611b605901c7d5d05b6b8f5d04a6ceb0962aa • CWE-476: NULL Pointer Dereference •
