| CVE-2020-11261 | Local Privilege Escalation via Memory Corruption in Qualcomm Snapdragon Chipsets CVE-2020-11261 is an improper input validation flaw (CWE-20/CWE-787, resulting in memory corruption/out-of-bounds writes) in the memory-allocation handling of firmware across a wide range of Qualcomm Snapdragon chipsets. It is triggered when a user application requests a memory allocation of a huge size and the affected component fails to properly return an error; a local attacker — such as a malicious or compromised app already running on the device — can leverage this to escalate privileges. Successful exploitation yields elevated privileges with high impact on confidentiality, integrity, and availability (CVSS 3.1 base score 7.8, local attack vector, no user interaction required). Affected platforms span the Snapdragon Auto, Compute, Connectivity, Consumer IoT, Industrial IoT, Mobile, Voice & Music, and Wearables product lines, including widely deployed entry-level mobile SoCs and connectivity chips. CISA added the flaw to its Known Exploited Vulnerabilities catalog on 2021-12-01, confirming in-the-wild exploitation; it was quietly patched in Android security updates alongside related Arm and Qualcomm zero-days, no public PoC is known, and EPSS estimates a 1.8% probability of exploitation in the next 30 days. Do: Apply updated Qualcomm firmware and driver packages per the vendor advisory, as required by CISA's KEV listing, and ensure Android devices receive the OEM security updates containing the fix. Inventory devices built on the listed chipsets (e.g., APQ8009, APQ8017, APQ8053, APQ8096AU) and confirm they run patched builds; there is no workaround beyond patching, since a local malicious app is sufficient to trigger the flaw. | 7.8 | 2% | KEV |

US tech giant Google said today it detected signs that a small number of Android device owners have been attacked using a vulnerability in the Android operating system that was patched in January 2021. Tracked as CVE-2020-11261, this is a bug in the Qualcomm graphics component that ships with Android devices that use Qualcomm chipsets. According to the Qualcomm changelog, the vulnerability can be used to trigger a memory corruption error when a malicious app requests access to a large portion of the device's memory. The bug can only be exploited with local access to the device — which means that in order to trigger an error, the attacker must deliver their malicious code through another app already installed on the user's device or through physical access to a smartphone. This usually requires complex attack scenarios, but requirements that at least one threat actor appears to have managed to achieve, according to Ben Hawkes, technical lead of Project Zero, one of Google's security teams, who disclosed the attacks earlier today. "Note: There are indications that CVE-2020-11261 may be under limited, targeted exploitation." https://t.co/NDFjKdfalz Details about the attacks, the threat actor(s) behind them, and the victims have not been shared. A source familiar with the vulnerability told The Record the attacks are still under investigation by the Project Zero team together with Google's Threat Analysis Group. It is unclear if the attacks using the CVE-2020-11261 security flaw —called an n-day vulnerability— are related to a global hacking campaign that Google disclosed last week. Google said last Thursday that a mysterious threat actor used a collection of 11 zero-days and multiple n-day vulnerabilities to attack Android, iOS, and Windows users. While Google said the attacks were small in scale, Android users who'd like to be sure they can't be targeted with this bug either now or later down the road are advised to apply the Android January 2021 security patches, which include the necessary fixes. Usually, Android security updates come with the necessary third-party firmware patches, but some devices might not be eligible for over-the-air firmware updates, and device owners might need to look and download patches manually. Qualcomm listed the following chipsets as being affected, for which device owners might need to look for updates if their device is not getting automatic security updates: APQ8009W, APQ8017, APQ8053, AQT1000, AR8031, AR8035, CSR8811, CSRA6620, CSRA6640, FSM10055, FSM10056, IPQ6010, IPQ6018, IPQ6028, IPQ8074A, IPQ8076A, IPQ8174, MSM8909W, MSM8917, MSM8953, PM215, PM3003A, PM4125, PM439, PM456, PM6125, PM6150, PM6150A, PM6150L, PM6250, PM6350, PM640A, PM640L, PM640P, PM660, PM660A, PM660L, PM7150A, PM7150L, PM7250, PM7250B, PM7350C, PM8004, PM8005, PM8008, PM8009, PM8150, PM8150A, PM8150B, PM8150C, PM8150L, PM8250, PM8350, PM8350B, PM8350BH, PM8350BHS, PM8350C, PM855, PM855B, PM855L, PM855P, PM8909, PM8937, PM8953, PM8998, PMC1000H, PMD9655, PMI632, PMI8937, PMI8952, PMI8998, PMK7350, PMK8002, PMK8003, PMK8350, PMM6155AU, PMM8155AU, PMM855AU, PMP8074, PMR525, PMR735A, PMR735B, PMW3100, PMX50, PMX55, QAT3514, QAT3516, QAT3518, QAT3519, QAT3522, QAT3550, QAT3555, QAT5515, QAT5516, QAT5522, QAT5533, QAT5568, QBT1500, QBT2000, QCA4024, QCA6175A, QCA6310, QCA6335, QCA6390, QCA6391, QCA6420, QCA6421, QCA6426, QCA6430, QCA6431, QCA6436, QCA6564, QCA6564A, QCA6564AU, QCA6574, QCA6574A, QCA6574AU, QCA6584AU, QCA6595, QCA6595AU, QCA6696, QCA8072, QCA8075, QCA8081, QCA8337, QCC1110, QCN5021, QCN5022, QCN5024, QCN5052, QCN5054, QCN5124, QCN5154, QCN9000, QCN9022, QCN9024, QCN9074, QCS405, QCS410, QCS610, QDM2301, QDM2302, QDM2305, QDM2307, QDM2308, QDM2310, QDM3301, QDM3302, QDM4643, QDM4650, QDM5579, QDM5620, QDM5621, QDM5650, QDM5652, QDM5670, QDM5671, QDM5677, QDM5679, QET4100, QET4101, QET4200AQ, QET5100, QET5100M, QET6100, QET6110, QFE2101, QFE2520, QFE2550, QFE3340, QFE4301, QFE4302, QFE4303, QFE4305, QFE4308, QFE4309, QFE4320, QFE4373FC, QFS2530, QFS2580, QFS2608, QFS2630, QLN1020, QLN1021AQ, QLN1030, QLN1031, QLN1036AQ, QLN4640, QLN4642, QLN4650, QLN5020, QLN5030, QLN5040, QPA2625, QPA4340, QPA4360, QPA4361, QPA5373, QPA5461, QPA5580, QPA5581, QPA6560, QPA8673, QPA8675, QPA8686, QPA8801, QPA8802, QPA8803, QPA8821, QPA8842, QPM2630, QPM4621, QPM4630, QPM4640, QPM4641, QPM4650, QPM5541, QPM5577, QPM5579, QPM5620, QPM5621, QPM5641, QPM5657, QPM5658, QPM5670, QPM5677, QPM5679, QPM5870, QPM5875, QPM6325, QPM6375, QPM6582, QPM6585, QPM6621, QPM6670, QPM8820, QPM8830, QPM8870, QPM8895, QSM7250, QSM8250, QSW6310, QSW8573, QSW8574, QTC410S, QTC800H, QTC800S, QTC801S, QTM525, QTM527, Qualcomm215, RSW8577, SA515M, SA6145P, SA6155, SA6155P, SA8155, SA8155P, SD 675, SD 8C, SD 8CX, SD205, SD210, SD429, SD439, SD460, SD632, SD660, SD662, SD665, SD670, SD675, SD690 5G, SD710, SD720G, SD730, SD750G, SD765, SD765G, SD768G, SD845, SD855, SD865 5G, SD888 5G, SDA429W, SDR051, SDR052, SDR425, SDR660, SDR660G, SDR675, SDR735, SDR735G, SDR8150, SDR8250, SDR865, SDW3100, SDX50M, SDX55, SDX55M, SDXR1, SDXR2 5G, SM4125, SM4350, SM6250, SM6250P, SM7250P, SM7350, SMB1351, SMB1354, SMB1355, SMB1358, SMB1380, SMB1381, SMB1390, SMB1394, SMB1395, SMB1396, SMB1398, SMB2351, SMR525, SMR526, WCD9326, WCD9335, WCD9340, WCD9341, WCD9370, WCD9371, WCD9375, WCD9380, WCD9385, WCN3610, WCN3615, WCN3620, WCN3660B, WCN3680B, WCN3910, WCN3950, WCN3980, WCN3988, WCN3990, WCN3991, WCN3998, WCN3999, WCN6740, WCN6750, WCN6850, WCN6851, WCN6856, WGR7640, WSA8810, WSA8815, WSA8830, WSA8835, WTR2955, WTR2965, WTR3925, WTR4905, WTR5975, WTR6955
