CyberRota Analysis
AI-GeneratedA use-after-free vulnerability exists in the Trusted Application loader of OP-TEE OS versions up to 4.10.0, allowing attackers with access to load signed Trusted Applications to corrupt secure-world kernel memory. By setting the TA_FLAG_CONCURRENT flag, an attacker can create concurrent sessions that improperly manage shared contexts, potentially leading to memory corruption and instability in secure operations. Organizations utilizing OP-TEE OS should prioritize patching to mitigate potential exploitation risks associated with this vulnerability.

Original NVD Description
OP-TEE OS through 4.10.0, fixed in commit 8794043, contains a use-after-free vulnerability in the Trusted Application loader that allows attackers with the ability to load a signed Trusted Application to corrupt secure-world kernel memory by setting the TA_FLAG_CONCURRENT flag in a user TA signed header. Attackers can cause two concurrent sessions to operate on the same shared context without locking, corrupting the uctx->vm_info.regions list during memref parameter mapping and unmapping to free vm_region nodes still in use, resulting in a use-after-free in S-EL1 secure-world kernel memory.
