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-2021-34866

A vulnerability was found in Linux Kernel, where a type confusion problem in checkmapfunccompatibility may lead to free arbitrary kernel memory. Mitigation The default Red Hat Enterprise Linux kernel prevents unprivileged users from being able to use eBPF by the kernel.unprivilegedbpfdisabled...

OESA-2021-1379 kernel security update

The Linux Kernel, the operating system core itself. Security Fixes: A flaw was found in the Linux kernel. Measuring usage of the shared memory does not scale with large shared memory segment counts which could lead to resource exhaustion and DoS.CVE-2021-3669 CVE-2021-3764 CVE-2021-3744...

kernel: powerpc: KVM guest OS users can cause host OS memory corruption

A flaw was found on the Linux kernel. On the PowerPC platform, the KVM guest allows the OS users to cause host OS memory corruption via rtasargs.nargs. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability...

CVE-2021-42252

The CVE-2021-42252 issue affects the Linux kernel up to version 5.14.5 in aspeed_lpc_ctrl_mmap (drivers/soc/aspeed/aspeed-lpc-ctrl.c). A memory overwrite can occur via the Aspeed LPC control interface when a comparison uses non-memory-size values, enabling a local attacker to potentially escalate...
