Description

In the Linux kernel, the following vulnerability has been resolved: RDMA/mana: Validate rx_hash_key_len Sashiko points out that rx_hash_key_len comes from a uAPI structure and is blindly passed to memcpy, allowing the userspace to trash kernel memory. Bounds check it so the memcpy cannot overflow.

Affected configurations

• linux linux kernel (>= 6.2 < 6.6.141) • linux linux kernel (>= 6.7 < 6.12.88) • linux linux kernel (>= 6.13 < 6.18.30) • linux linux kernel (>= 6.19 < 7.0.7) • linux linux kernel 7.1
