CVE-2020-27820 – kernel: use-after-free in nouveau kernel module
https://notcve.org/view.php?id=CVE-2020-27820
02 Nov 2021 — A vulnerability was found in Linux kernel, where a use-after-frees in nouveau's postclose() handler could happen if removing device (that is not common to remove video card physically without power-off, but same happens if "unbind" the driver). Se ha encontrado una vulnerabilidad en el kernel de Linux, en la que un uso de memoria previamente liberada en el manejador postclose() de nouveau podría ocurrir si se quita el dispositivo (que no es común quitar la tarjeta de vídeo físicamente sin apagar, pero lo mi... • https://bugzilla.redhat.com/show_bug.cgi?id=1901726 • CWE-416: Use After Free •

21 Oct 2021 — dp_link_settings_write in drivers/gpu/drm/amd/display/amdgpu_dm/amdgpu_dm_debugfs.c in the Linux kernel through 5.14.14 allows a heap-based buffer overflow by an attacker who can write a string to the AMD GPU display drivers debug filesystem. There are no checks on size within parse_write_buffer_into_params when it uses the size of copy_from_user to copy a userspace buffer into a 40-byte heap buffer. la función dp_link_settings_write en el archivo drivers/gpu/drm/amd/display/amdgpu_dm/amdgpu_dm_debugfs.c en... • https://github.com/docfate111/CVE-2021-42327 • CWE-787: Out-of-bounds Write •
CVE-2021-42739 – kernel: Heap buffer overflow in firedtv driver

CVE-2021-34866 – Linux Kernel eBPF Type Confusion Privilege Escalation Vulnerability
https://notcve.org/view.php?id=CVE-2021-34866
13 Oct 2021 — This vulnerability allows local attackers to escalate privileges on affected installations of Linux Kernel 5.14-rc3. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability. The specific flaw exists within the handling of eBPF programs. The issue results from the lack of proper validation of user-supplied eBPF programs, which can result in a type confusion condition. An attacker can leverage this vulnerability to escalate privilege... • https://security.netapp.com/advisory/ntap-20220217-0008 • CWE-697: Incorrect Comparison CWE-843: Access of Resource Using Incompatible Type ('Type Confusion') •

11 Oct 2021 — An issue was discovered in aspeed_lpc_ctrl_mmap in drivers/soc/aspeed/aspeed-lpc-ctrl.c in the Linux kernel before 5.14.6. Local attackers able to access the Aspeed LPC control interface could overwrite memory in the kernel and potentially execute privileges, aka CID-b49a0e69a7b1. This occurs because a certain comparison uses values that are not memory sizes.
