The vulnerability of the cpia2_remap_buffer function in the Linux operating system allows a hacker to gain access to read and write physical pages in the kernel, thereby enhancing their privileges.

The vulnerability of the cpia2remapbuffer function drivers/media/usb/cpia2/cpia2core.c in the Linux kernel is related to integer overflow. Exploiting this vulnerability can allow an attacker to gain access to read and write operations on physical pages in the kernel, thereby enhancing their...

kernel: TLB flush happens too late on mremap

Since Linux kernel version 3.2, the mremap syscall performs TLB flushes after dropping pagetable locks. If a syscall such as ftruncate removes entries from the pagetables of a task that is in the middle of mremap, a stale TLB entry can remain for a short time that permits access to a physical pag...

DEBIAN-CVE-2019-18675

The Linux kernel through 5.3.13 has a startoffset+size Integer Overflow in cpia2remapbuffer in drivers/media/usb/cpia2/cpia2core.c because cpia2 has its own mmap implementation. This allows local users with /dev/video0 access to obtain read and write permissions on kernel physical pages, which ca...

Vulnerability of the `init_agent2TA_context` function in the `TEEOS.img` file (offset 0x13949C) of the TEE OS Trusted Core component in the microprogramming system of the Huawei Mate 9 Pro mobile phone. This vulnerability allows an attacker to trigger a service failure or to read the virtual memory of the TEE OS at arbitrary addresses.

The vulnerability of the initagent2TAcontext function in the TEEOS.img file with a offset of 0x13949C in the SMC handler of the TEE OS Trusted Core in the microprogramming of the Huawei Mate 9 Pro mobile phone is related to the lack of validation for the remap value passed in the request...
