Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description The Linux kernel contained an issue in the crypto/omap subsystem where scatterlists were incorrectly allocated in the omap crypto copy sg lists() function. The allocation was for pointers to scatterlists instead of the scatterlist objects themselves, resulting in an allocation that was four times too small. The fix involves using sizeof(*new sg) to obtain the correct object size during allocation.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
