Summary
In the Linux kernel, the following vulnerability has been resolved: net: enetc: check the number of BDs needed for xdp_frame The size of xdp_redirect_arr array is ENETC_MAX_SKB_FRAGS.
However, the number of fragments contained in xdp_frame may be greater than or equal to ENETC_MAX_SKB_FRAGS, which will cause the access to xdp_redirect_arr to be out of bounds. A flaw was found in the Linux kernel's enetc network driver.
This vulnerability occurs in the eXpress Data Path (XDP) frame processing, where the driver fails to properly check the number of fragments in an XDP frame against the allocated buffer size.
A remote attacker could exploit this out-of-bounds memory access by sending specially crafted network packets, potentially leading to a denial of service or arbitrary code execution. Red Hat severity: Moderate — CVSS 7 (CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H).
Weakness: CWE-805. Affected Red Hat products: Red Hat Enterprise Linux 10.
