https://notcve.org/view.php?id=CVE-2024-42123
In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: fix double free err_addr pointer warnings In amdgpu_umc_bad_page_polling_timeout, the amdgpu_umc_handle_bad_pages will be run many times so that double free err_addr in some special case. So set the err_addr to NULL to avoid the warnings. A vulnerability was found in the amdgpu_umc_handle_bad_pages() function in the Linux kernel's amdgpu driver. If the function is called multiple times in quick succession, a double free error can occur because the err_data->err_addr pointer that is being freed is not being set to NULL in between calls. This could lead to memory corruption or crashes. • https://git.kernel.org/stable/c/8e24beb3c2b08a4763f920399a9cc577ed440a1a https://git.kernel.org/stable/c/506c245f3f1cd989cb89811a7f06e04ff8813a0d https://access.redhat.com/security/cve/CVE-2024-42123 https://bugzilla.redhat.com/show_bug.cgi?id=2301488 • CWE-415: Double Free •

In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Check index msg_id before read or write [WHAT] msg_id is used as an array index and it cannot be a negative value, and therefore cannot be equal to MOD_HDCP_MESSAGE_ID_INVALID (-1). [HOW] Check whether msg_id is valid before reading and setting.
