Description

In the Linux kernel, the following vulnerability has been resolved: iommu/vt-d: Clean up si_domain in the init_dmars() error path A splat from kmem_cache_destroy() was seen with a kernel prior to commit ee2653bbe89d ("iommu/vt-d: Remove domain and devinfo mempool") when there was a failure in init_dmars(), because the iommu_domain cache still had objects. While the mempool code is now gone, there still is a leak of the si_domain memory if init_dmars() fails. So clean up si_domain in the init_dmars() error path.

Affected configurations

• linux linux kernel (>= 4.2 < 4.14.298) • linux linux kernel (>= 4.15 < 4.19.264) • linux linux kernel (>= 4.20 < 5.4.221) • linux linux kernel (>= 5.5 < 5.10.152) • linux linux kernel (>= 5.11 < 5.15.76) • linux linux kernel (>= 5.16 < 6.0.6) • linux linux kernel 6.1
