CVE-2021-47153

CVE-2021-47153 involves the Linux kernel i2c: i801 driver. The issue occurs when a KILL-recover/bus-reset process triggers an interrupt that the i801_isr cannot handle, potentially causing an out-of-bounds memory access in block transactions. The connected MiracleLinux advisories (AXSA) reference...

CVE-2021-47153 i2c: i801: Don't generate an interrupt on bus reset

In the Linux kernel, the following vulnerability has been resolved: i2c: i801: Don't generate an interrupt on bus reset Now that the i2c-i801 driver supports interrupts, setting the KILL bit in a attempt to recover from a timed out transaction triggers an interrupt. Unfortunately, the interrupt...
