Detailsinfo

A vulnerability was found in Linux Kernel up to 6.9.9 and classified as problematic. The impact remains unknown. The summary by CVE is:

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.

The advisory is shared at git.kernel.org. The identification of this vulnerability is CVE-2024-41044 since 07/12/2024. Technical details are known, but no exploit is available.
