5.5 MEDIUM — CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H

Description

In the Linux kernel, the following vulnerability has been resolved: ppp: reject claimed-as-LCP but actually malformed packets Since 'ppp_async_encode()' assumes valid LCP packets (with code from 1 to 7 inclusive), add 'ppp_check_packet()' to ensure that LCP packet has an actual body beyond PPP_LCP header bytes, and reject claimed-as-LCP but actually malformed data otherwise.

Affected configurations

• linux linux kernel (>= 2.6.13 < 4.19.318) • linux linux kernel (>= 4.20 < 5.4.280) • linux linux kernel (>= 5.5 < 5.10.222) • linux linux kernel (>= 5.11 < 5.15.163) • linux linux kernel (>= 5.16 < 6.1.100) • linux linux kernel (>= 6.2 < 6.6.41) • linux linux kernel (>= 6.7 < 6.9.10) • linux linux kernel 2.6.12 • linux linux kernel 6.10
