Vulnerability from variot - Updated: 2023-12-18 12:56

The msm gpu driver for custom Linux kernels on the Xiaomi perseus-p-oss MIX 3 device through 2018-11-26 has an integer overflow and OOPS because of missing checks of the count argument in sde_evtlog_filter_write in drivers/gpu/drm/msm/sde_dbg.c. This is exploitable for a device crash via a syscall by a crafted application on a rooted device. Xiaomi perseus-p-oss MIX 3 The device contains an integer overflow vulnerability.Service operation interruption (DoS) There is a possibility of being put into a state. Xiaomiperseus-p-ossMIX3 is a smartphone from China Xiaomi Technology. An integer overflow vulnerability exists in the sde_evtlog_filter_write method of the drivers/gpu/drm/msm/sde_dbg.c file in Xiaomiperseus-p-ossMIX32018-11-26 and earlier. The vulnerability stems from the program failing to check the 'count' parameter. The attacker can Use this vulnerability to cause an OOPS error
