CVE-2023-53315

8.8 · HIGH
Published Sep 16, 2025 linux CWE-401 EPSS 0.23% (14th pctl)

Overview

CVE-2023-53315 is a high-severity vulnerability affecting linux linux_kernel. It was published on September 16, 2025 and has a CVSS 3.1 base score of 8.8 (HIGH).

This vulnerability has a CVSS 3.1 base score of 8.8, rated HIGH. It requires local or adjacent network access to exploit. No authentication or special privileges are required for exploitation.

Technical Description

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

wifi: ath11k: Fix SKB corruption in REO destination ring

While running traffics for a long time, randomly an RX descriptor

filled with value "0" from REO destination ring is received.

This descriptor which is invalid causes the wrong SKB (SKB stored in

the IDR lookup with buffer id "0") to be fetched which in turn

causes SKB memory corruption issue and the same leads to crash

after some time.

Changed the start id for idr allocation to "1" and the buffer id "0"

is reserved for error validation. Introduced Sanity check to validate

the descriptor, before processing the SKB.

Crash Signature :

Unable to handle kernel paging request at virtual address 3f004900

PC points to "b15_dma_inv_range+0x30/0x50"

LR points to "dma_cache_maint_page+0x8c/0x128".

The Backtrace obtained is as follows:

[<8031716c>] (b15_dma_inv_range) from [<80313a4c>] (dma_cache_maint_page+0x8c/0x128)

[<80313a4c>] (dma_cache_maint_page) from [<80313b9

Remediation

Check the references section for vendor advisories and patches from linux. Update linux_kernel to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
