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.

Upgrade torvalds/linux to version 6.1.191, 6.6.160, 6.9.9 or higher.
Overview
Affected versions of this package are vulnerable to Double Free in the amdgpu_umc_bad_page_polling_timeout process. An attacker can cause memory corruption, information disclosure, or denial of service by triggering a double free of the err_addr pointer through repeated hardware error events and manipulation of GPU compute jobs. This is only exploitable if a real uncorrectable ECC/poison event occurs in GPU HBM and, on a later poll iteration, amdgpu_dpm_get_ecc_info() returns a value other than 0 or -EOPNOTSUPP, which are hardware/firmware states outside attacker control.
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
