CVE-2023-52762: Linux Kernel

Medium severity, CVSS 5.5. EPSS: 0.2% chance of exploitation in the next 30 days.

In the Linux kernel, the following vulnerability has been resolved: virtio-blk: fix implicit overflow on virtio_max_dma_size The following codes have an implicit conversion from size_t to u32: (u32)max_size = (size_t)virtio_max_dma_size(vdev); This may lead overflow, Ex (size_t)4G -> (u32)0. Once virtio_max_dma_size() has a larger size than U32_MAX, use U32_MAX instead.

Affected products

• Linux Linux Kernel: before 5.15.140 (fixed in 5.15.140); from 5.16, before 6.1.64 (fixed in 6.1.64); from 6.2, before 6.5.13 (fixed in 6.5.13); from 6.6, before 6.6.3 (fixed in 6.6.3)
