Linux Kernel 64 Bit AR-RSC Register Access Validation Vulnerability
The Linux Kernel for 64-bit architectures is prone to an access-validation vulnerability. The issue occurs because the software fails to restrict access to the 'ar.rsc' register (register stack engine control register) by the 'restore_sigcontext' function. Immediate consequences of exploitation would likely be a denial of service; other attacks are also possible. |
