CVE-2023-28576

The buffer obtained from kernel APIs such as cammemgetcpubuf may be readable/writable in userspace after kernel accesses it. In other words, user mode may race and modify the packet header e.g. header.count, causing checks e.g. size checks in kernel code to be invalid. This may lead to...

CVE-2023-28576

CVE-2023-28576 describes a TOCTOU race in Qualcomm camera kernel driver where a buffer obtained from kernel APIs such as cam_mem_get_cpu_buf() may be readable/writable in userspace after the kernel accesses it. This can allow user-mode modification of packet headers (e.g., header.count) and inval...
