CVE-2026-53075

A flaw was found in the Linux kernel's Point-to-Point Protocol PPP subsystem. A local unprivileged user can exploit this vulnerability by creating a new user namespace and bypassing authorization checks for unattached administrative input/output controls ioctls. This allows the user to perform...

CVE-2026-53075 ppp: require CAP_NET_ADMIN in target netns for unattached ioctls

In the Linux kernel, the following vulnerability has been resolved: ppp: require CAPNETADMIN in target netns for unattached ioctls /dev/ppp open is currently authorized against file-fcred-userns, while unattached administrative ioctls operate on current-nsproxy-netns. As a result, a local...

CVE-2026-46306

In the Linux kernel, the following vulnerability has been resolved: flowdissector: do not dissect PPPoE PFC frames RFC 2516 Section 7 states that Protocol Field Compression PFC is NOT RECOMMENDED for PPPoE. In practice, pppd does not support negotiating PFC for PPPoE sessions, and the flow...

CVE-2026-45842

A flaw was found in the Linux kernel's SLIP Serial Line Internet Protocol and PPP Point-to-Point Protocol components. An unprivileged local user can exploit this vulnerability by manipulating the PPPIOCSMAXCID ioctl to configure the SLIP Compressed Header SLHC state incorrectly. This...

CVE-2026-45842

CVE-2026-45842 concerns the Linux kernel slip module. When rslots are configured to 0 (no receive compression), the code may allocate a NULL rstate and set rslot_limit to 0. The receive path does not guard against this, causing slhc_uncompress() to dereference comp->rstate[x] if the VJ header ...
