CVE-2016-7910 [HIGH] CWE-416 kernel: Use after free in seq file
kernel: Use after free in seq file
Use-after-free vulnerability in the disk_seqf_stop function in block/genhd.c in the Linux kernel before 4.7.1 allows local users to gain privileges by leveraging the execution of a certain stop operation even if the corresponding start operation had failed.
A flaw was found in the Linux kernel's implementation of seq_file where a local attacker could manipulate memory in the put() function pointer. This could lead to memory corruption and possible privileged escalation.
Statement: This issue does not affect the Linux kernel packages as shipped with Red Hat Enterprise Linux 5 as the code which can trigger the flaw is not present in the products listed.
This issue affects the Linux kernel packages as shipped with Red Hat Enterprise Linux 6, 7 and MRG-2.
