Aug 4 RESCORED — CVE-2022-49094 (Linux). CVSS 9.8 → 7.1 (NVD).
Description
In the Linux kernel, the following vulnerability has been resolved:
net/tls: fix slab-out-of-bounds bug in decrypt_internal
The memory size of tls_ctx->rx.iv for AES128-CCM is 12 setting in
tls_set_sw_offload(). The return value of crypto_aead_ivsize()
for "ccm(aes)" is 16. So memcpy() require 16 bytes from 12 bytes
memory space will trigger slab-out-of-bounds bug as following:
