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-2021-42252 – Ubuntu Security Notice USN-5137-1
https://notcve.org/view.php?id=CVE-2021-42252
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.

CVE-2021-41864 – kernel: eBPF multiplication integer overflow in prealloc_elems_and_freelist() in kernel/bpf/stackmap.c leads to out-of-bounds write
https://notcve.org/view.php?id=CVE-2021-41864
01 Oct 2021 — prealloc_elems_and_freelist in kernel/bpf/stackmap.c in the Linux kernel before 5.14.12 allows unprivileged users to trigger an eBPF multiplication integer overflow with a resultant out-of-bounds write. prealloc_elems_and_freelist en kernel/bpf/stackmap.c en el kernel de Linux antes de la versión 5.14.12 permite a usuarios sin privilegios desencadenar un desbordamiento de enteros en la multiplicación de eBPF con una escritura fuera de los límites resultante.

CVE-2021-3753 – kernel: a race out-of-bound read in vt
https://notcve.org/view.php?id=CVE-2021-3753
28 Sep 2021 — A race problem was seen in the vt_k_ioctl in drivers/tty/vt/vt_ioctl.c in the Linux kernel, which may cause an out of bounds read in vt as the write access to vc_mode is not protected by lock-in vt_ioctl (KDSETMDE). The highest threat from this vulnerability is to data confidentiality.

28 Sep 2021 — An out-of-bounds (OOB) memory read flaw was found in the Qualcomm IPC router protocol in the Linux kernel. A missing sanity check allows a local attacker to gain access to out-of-bounds memory, leading to a system crash or a leak of internal kernel information. The highest threat from this vulnerability is to system availability.

28 Sep 2021 — A NULL pointer dereference flaw was found in the btrfs_rm_device function in fs/btrfs/volumes.c in the Linux Kernel, where triggering the bug requires ‘CAP_SYS_ADMIN’. This flaw allows a local attacker to crash the system or leak kernel internal information. The highest threat from this vulnerability is to system availability.

20 Sep 2021 — arch/mips/net/bpf_jit.c in the Linux kernel before 5.4.10 can generate undesirable machine code when transforming unprivileged cBPF programs, allowing execution of arbitrary code within the kernel context. This occurs because conditional branches can exceed the 128 KB limit of the MIPS architecture. arch/mips/net/bpf_jit.c en el kernel de Linux anterior a la versión 5.4.10 puede generar código máquina no deseado al transformar programas cBPF sin privilegios, permitiendo la ejecución de código arbitrario den... • http://www.openwall.com/lists/oss-security/2021/09/15/5 •

19 Sep 2021 — loop_rw_iter in fs/io_uring.c in the Linux kernel 5.10 through 5.14.6 allows local users to gain privileges by using IORING_OP_PROVIDE_BUFFERS to trigger a free of a kernel buffer, as demonstrated by using /proc/
CVE-2014-0069 – kernel: cifs: incorrect handling of bogus user pointers during uncached writes
https://notcve.org/view.php?id=CVE-2014-0069
28 Feb 2014 — The cifs_iovec_write function in fs/cifs/file.c in the Linux kernel through 3.13.5 does not properly handle uncached write operations that copy fewer than the requested number of bytes, which allows local users to obtain sensitive information from kernel memory, cause a denial of service (memory corruption and system crash), or possibly gain privileges via a writev system call with a crafted pointer.
