Linux kernel local security bypass vulnerability (CNVD-2017-02602)

The Linux kernel is the kernel used by the operating system Linux, released by the Linux Foundation in the United States. A security vulnerability exists in the 'doshmat' function in the ipc/shm.c file in Linux kernel versions 4.9.12 and earlier. A local attacker can exploit this vulnerability to...

DEBIAN-CVE-2017-5669

The doshmat function in ipc/shm.c in the Linux kernel through 4.9.12 does not restrict the address calculated by a certain rounding operation, which allows local users to map page zero, and consequently bypass a protection mechanism that exists for the mmap system call, by making crafted shmget a...

kernel: ipc/shm.c: reading uninitialized stack memory

The copyshmidtouser function in ipc/shm.c in the Linux kernel before 2.6.37-rc1 does not initialize a certain structure, which allows local users to obtain potentially sensitive information from kernel stack memory via vectors related to the shmctl system call and the "old shm interface."...
