Doc Text:	A heap‑overflow vulnerability was discovered in the linux kernel e1000e driver’s e1000_set_eeprom() function, insufficient validation of the requested length for an EEPROM change could allow a local, low‑privilege user to trigger memory corruption (heap overflow). A local unprivileged user with access to the driver could exploit this flaw to cause memory corruption, potentially leading to confidentiality, integrity, and availability damage.	Story Points:	---

Description OSIDB Bzimport 2025-10-01 08:01:40 UTC

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

e1000e: fix heap overflow in e1000_set_eeprom

Fix a possible heap overflow in e1000_set_eeprom function by adding
input validation for the requested length of the change in the EEPROM.
In addition, change the variable type from int to size_t for better
code practices and rearrange declarations to RCT.
