CVE-2022-48947

CVE-2022-48947 is a Linux kernel vulnerability related to Bluetooth L2CAP u8 overflow. By repeatedly sending L2CAP_CONF_REQ, chan->num_conf_rsp could wrap at 255. The fix adds a boundary check using L2CAP_MAX_CONF_RSP to prevent overflow. Connected advisories (e.g., Unity Linux/Astra Linux ent...

CVE-2022-48947 Bluetooth: L2CAP: Fix u8 overflow

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: L2CAP: Fix u8 overflow By keep sending L2CAPCONFREQ packets, chan-numconfrsp increases multiple times and eventually it will wrap around the maximum number i.e., 255. This patch prevents this by adding a boundary check...
