CVSS: -EPSS: 0%CPEs: 5EXPL: 0CVE-2024-47727 – x86/tdx: Fix "in-kernel MMIO" check
https://notcve.org/view.php?id=CVE-2024-47727
In the Linux kernel, the following vulnerability has been resolved: x86/tdx: Fix "in-kernel MMIO" check TDX only supports kernel-initiated MMIO operations. The handle_mmio() function checks if the #VE exception occurred in the kernel and rejects the operation if it did not. However, userspace can deceive the kernel into performing MMIO on its behalf. For example, if userspace can point a syscall to an MMIO address, syscall does get_user() or put_user() on it, triggering MMIO #VE. The kernel will treat the #VE as in-kernel MMIO. Ensure that the target MMIO address is within the kernel before decoding instruction. • https://git.kernel.org/stable/c/31d58c4e557d46fa7f8557714250fb6f89c941ae https://git.kernel.org/stable/c/25703a3c980e21548774eea8c8a87a75c5c8f58c https://git.kernel.org/stable/c/4c0c5dcb5471de5fc8f0a1c4980e5815339e1cee https://git.kernel.org/stable/c/18ecd5b74682839e7cdafb7cd1ec106df7baa18c https://git.kernel.org/stable/c/bca2e29f7e26ce7c3522f8b324c0bd85612f68e3 https://git.kernel.org/stable/c/d4fc4d01471528da8a9797a065982e05090e1d81 •

https://notcve.org/view.php?id=CVE-2024-47723
In the Linux kernel, the following vulnerability has been resolved: jfs: fix out-of-bounds in dbNextAG() and diAlloc() In dbNextAG() , there is no check for the case where bmp->db_numag is greater or same than MAXAG due to a polluted image, which causes an out-of-bounds. Therefore, a bounds check should be added in dbMount(). And in dbNextAG(), a check for the case where agpref is greater than bmp->db_numag should be added, so an out-of-bounds exception should be prevented. Additionally, a check for the case where agno is greater or same than MAXAG should be added in diAlloc() to prevent out-of-bounds. • https://git.kernel.org/stable/c/1da177e4c3f41524e886b7f1b8a0c1fc7321cac2 https://git.kernel.org/stable/c/0338e66cba272351ca9d7d03f3628e390e70963b https://git.kernel.org/stable/c/ead82533278502428883085a787d5a00f15e5eb9 https://git.kernel.org/stable/c/6ce8b6ab44a8b5918c0ee373d4ad19d19017931b https://git.kernel.org/stable/c/c1ba4b8ca799ff1d99d01f37d7ccb7d5ba5533d2 https://git.kernel.org/stable/c/128d5cfdcf844cb690c9295a3a1c1114c21fc15a https://git.kernel.org/stable/c/96855f40e152989c9e7c20c4691ace5581098acc https://git.kernel.org/stable/c/e63866a475562810500ea7f784099bfe3 •

CVSS: -EPSS: 0%CPEs: 6EXPL: 0CVE-2024-47720 – drm/amd/display: Add null check for set_output_gamma in dcn30_set_output_transfer_func
https://notcve.org/view.php?id=CVE-2024-47720
In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Add null check for set_output_gamma in dcn30_set_output_transfer_func This commit adds a null check for the set_output_gamma function pointer in the dcn30_set_output_transfer_func function. Previously, set_output_gamma was being checked for nullity at line 386, but then it was being dereferenced without any nullity check at line 401. This could potentially lead to a null pointer dereference error if set_output_gamma is indeed null. To fix this, we now ensure that set_output_gamma is not null before dereferencing it. We do this by adding a nullity check for set_output_gamma before the call to set_output_gamma at line 401. If set_output_gamma is null, we log an error message and do not call the function. This fix prevents a potential null pointer dereference error. drivers/gpu/drm/amd/amdgpu/.. • https://git.kernel.org/stable/c/d99f13878d6f9c286b13860d8bf0b4db9ffb189a https://git.kernel.org/stable/c/44948d3cb943602ba4a0b5ed3c91ae0525838fb1 https://git.kernel.org/stable/c/64886a4e6f1dce843c0889505cf0673b5211e16a https://git.kernel.org/stable/c/ddf9ff244d704e1903533f7be377615ed34b83e7 https://git.kernel.org/stable/c/84edd5a3f5fa6aafa4afcaf9f101f46426c620c9 https://git.kernel.org/stable/c/72ee32d0907364104fbcf4f68dd5ae63cd8eae9e https://git.kernel.org/stable/c/08ae395ea22fb3d9b318c8bde28c0dfd2f5fa4d2 •
