CVE-2023-52611
5.5 · MEDIUMOverview
CVE-2023-52611 is a medium-severity vulnerability affecting linux linux_kernel. It was published on March 18, 2024 and has a CVSS 3.1 base score of 5.5 (MEDIUM).
This vulnerability has a CVSS 3.1 base score of 5.5, rated MEDIUM. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.
Technical Description
In the Linux kernel, the following vulnerability has been resolved:
wifi: rtw88: sdio: Honor the host max_req_size in the RX path
Lukas reports skb_over_panic errors on his Banana Pi BPI-CM4 which comes
with an Amlogic A311D (G12B) SoC and a RTL8822CS SDIO wifi/Bluetooth
combo card. The error he observed is identical to what has been fixed
in commit e967229ead0e ("wifi: rtw88: sdio: Check the HISR RX_REQUEST
bit in rtw_sdio_rx_isr()") but that commit didn't fix Lukas' problem.
Lukas found that disabling or limiting RX aggregation works around the
problem for some time (but does not fully fix it). In the following
discussion a few key topics have been discussed which have an impact on
this problem:
- The Amlogic A311D (G12B) SoC has a hardware bug in the SDIO controller
which prevents DMA transfers. Instead all transfers need to go through
the controller SRAM which limits transfers to 1536 bytes
- rtw88 chips don't split incoming (RX) packets, so if a big packet is
received thi
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.
