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

Description The issue is related to a memory problem in the Linux kernel's wifi module, specifically with the vmm table in the wilc1000 struct. Enabling KASAN and running iperf tests reveals a slab-out-of-bounds error in the wilc wlan handle txq function. The error occurs due to a mismatch between the allocated size and the range of possible indexes used later, missing a multiplication by sizeof(u32). This results in writing data beyond the allocated range for vmm table.

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