Description OSIDB Bzimport 2026-02-18 16:03:20 UTC 
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.
