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.

NewCVE-2026-53386 (opens in a new tab)How to fix?
Upgrade SLES:16.0.0 kernel-kvmsmall to version 6.12.0-160000.37.1 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream kernel-kvmsmall package and not the kernel-kvmsmall package as distributed by SLES.
See How to fix? for SLES:16.0.0 relevant fixed versions and status.
In the Linux kernel, the following vulnerability has been resolved:
iio: adc: ti-ads1298: add bounds check to pga_settings index
ads1298_pga_settings has 7 elements but ADS1298_MASK_CH_PGA can yield values 0-7. If it yields a value >= 7, this causes an out-of-bounds array access. Add a bounds check and return -EINVAL if the index is out of range.
Note that the remaining value b111 is reserved so should not be seen in a correctly functioning system.
