CVE-2023-52690

Status: AnalyzedMedium (5.5)—

In the Linux kernel, the following vulnerability has been resolved:

powerpc/powernv: Add a null pointer check to scom_debug_init_one()

kasprintf() returns a pointer to dynamically allocated memory which can be NULL upon failure. Add a null pointer check, and release 'ent' to avoid memory leaks.

CVSS

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
