Description Karol Babioch 2018-03-08 14:05:29 UTC 
CVE-2018-7755

An issue was discovered in the fd_locked_ioctl function in
drivers/block/floppy.c in the Linux kernel through 4.15.7. The floppy driver
will copy a kernel pointer to user memory in response to the FDGETPRM ioctl. An
attacker can send the FDGETPRM ioctl and use the obtained kernel pointer to
discover the location of kernel code and data and bypass kernel security
protections such as KASLR.

Comment 6 Karasulli 2022-04-22 15:11:44 UTC 
Vulnerability was introduced in v2.6.34-rc2 and fixed in v4.19-rc5. So applicable branches:

   cve/linux-4.12 -- branch already contains the patch which needs to be updated.
   cve/linux-4.4
   cve/linux-3.0

The commit 65eea8edc3 is apparently backported to the affected branches [2] already (thanks Vasant). Let me move this forward per process [1] by resetting the assignee.
