Linux kernel offset pointer information disclosure
| linux-pointer-info-disclosure (16877) |  Medium Risk |
Description:
Linux kernel could allow a local attacker to obtain sensitive information, caused by a vulnerability when handling 64-bit file offset pointers. A local attacker could exploit this vulnerability to view portions of the kernel's memory.
