Threat Intelligence
The probability is the direct output of the EPSS model, and conveys an overall sense of the threat of exploitation in the wild. The percentile measures the EPSS probability relative to all known EPSS scores. Note: This data is updated daily, relying on the latest available EPSS model version. Check out the EPSS documentation for more details.

CVE-2022-50272 (opens in a new tab)How to fix?
Upgrade torvalds/linux to version 4.9.337, 4.14.303, 4.19.270, 5.4.229, 5.10.163, 5.15.86, 6.0.16, 6.1.2 or higher.
Overview
Affected versions of this package are vulnerable to NULL Pointer Dereference in the az6027_i2c_xfer function. An attacker can trigger a null pointer dereference by providing a crafted I2C message where the address is set to 0x99, the length is zero, and the buffer pointer is null, leading to a kernel crash.
Note: The Linux kernel project assigns a CVE to every bug fix it ships, whether or not the bug has been shown to be exploitable. This advisory was generated from that process and has not been individually assessed for exploitability. See the kernel's CVE process documentation: https://github.com/torvalds/linux/blob/master/Documentation/process/cve.rst
