Memory corruption while processing a GP command response. Rated high severity (CVSS 8.8), this vulnerability is low attack complexity. No vendor patch available.
Memory corruption in Qualcomm's PlayReady Trusted Application (TA) occurs when the TA processes crafted commands, and since the vulnerability is reachable only through the local trusted-execution environment it requires an attacker who can already run code on the device at app privilege level. Successful exploitation could corrupt memory within the Trusted Execution Environment and lead to code execution or integrity loss (CWE-131, Incorrect Calculation of Buffer Size), affecting a very broad range of Qualcomm chipsets across mobile, modem, IoT, automotive, compute, and wearable platforms. No public exploit code has been identified and EPSS is negligible (0.09%, 0th percentile), so this is an access-gated issue that matters most to devices that ship and rely on the affected PlayReady TA.
Memory corruption while performing finish HMAC operation when context is freed by keymaster. Rated high severity (CVSS 7.8), this vulnerability is low attack complexity. No vendor patch available.
Transient DOS while parsing IPv6 extension header when WLAN firmware receives an IPv6 packet that contains `IPPROTO_NONE` as the next header. Rated high severity (CVSS 7.5), this vulnerability is remotely exploitable, no authentication required, low attack complexity. No vendor patch available.
The session index variable in PCM host voice audio driver initialized before PCM open, accessed during event callback from ADSP and reset during PCM close may lead to race condition between event. Rated high severity (CVSS 7.8), this vulnerability is low attack complexity. No vendor patch available.
Memory corruption in HLOS while running playready use-case. Rated critical severity (CVSS 9.3), this vulnerability is no authentication required, low attack complexity. No vendor patch available.
Transient DOS while parsing a vender specific IE (Information Element) of reassociation response management frame. Rated high severity (CVSS 7.5), this vulnerability is remotely exploitable, no authentication required, low attack complexity. No vendor patch available.
Information disclosure when the trusted application metadata symbol addresses are accessed while loading an ELF in TEE. Rated medium severity (CVSS 6.5), this vulnerability is low attack complexity. No vendor patch available.
Memory Corruption in SPS Application while exporting public key in sorter TA. Rated high severity (CVSS 7.8), this vulnerability is low attack complexity. No vendor patch available.
Memory corruption in Audio while processing the VOC packet data from ADSP. Rated high severity (CVSS 7.8), this vulnerability is low attack complexity.
Memory corruption in WLAN HAL while processing devIndex from untrusted WMI payload. Rated high severity (CVSS 7.8), this vulnerability is low attack complexity. No vendor patch available.
Memory corruption in WLAN HAL while processing WMI-UTF command or FTM TLV1 command. Rated high severity (CVSS 7.8), this vulnerability is low attack complexity. No vendor patch available.
