QEMU: NULL dereference in ahci_commit_buf() leading to DoS

CVE-2019-12067 [MEDIUM] CWE-476 QEMU: NULL dereference in ahci_commit_buf() leading to DoS
QEMU: NULL dereference in ahci_commit_buf() leading to DoS
The ahci_commit_buf function in ide/ahci.c in QEMU allows attackers to cause a denial of service (NULL dereference) when the command header 'ad->cur_cmd' is null.
A NULL pointer dereference flaw was found in the QEMU emulator's IDE AHCI emulator. Exploitation of the flaw could occur while committing DMA buffer in ahci_commit_buf() if the command header 'ad->cur_cmd' was null. A privileged guest user could use this flaw to crash the QEMU process instance resulting in DoS. Reduced performance of the system is the highest threat to the system.
Statement: The qemu-kvm package versions as shipped with Red Hat Enterprise Linux 6 and 7 are not affected by this issue.

CVE-2019-12067 QEMU: NULL dereference in ahci_commit_buf() leading to DoS
QEMU emulator built with the AHCI emulator support is vulnerable to a NULL pointer dereference issue. It could occur while committing DMA buffer in ahci_commit_buf() if the command header 'ad->cur_cmd' is null.
A privileged guest user could use this flaw to crash the QEMU process instance resulting in DoS.
