DescriptionCVE.org

In the Linux kernel, the following vulnerability has been resolved:

crypto: omap - Allocate OMAP_CRYPTO_FORCE_COPY scatterlists correctly

The existing allocation of scatterlists in omap_crypto_copy_sg_lists() was allocating an array of scatterlist pointers, not scatterlist objects, resulting in a 4x too small allocation.

Use sizeof(*new_sg) to get the correct object size.

AnalysisAI

Memory allocation errors in the Linux kernel's OMAP crypto driver cause scatterlist objects to be undersized by 4x, enabling local authenticated attackers to trigger denial of service conditions through memory corruption. An attacker with local access and user-level privileges can exploit this miscalculation to crash the system or cause unpredictable kernel behavior. No patch is currently available for this vulnerability.
