The remote RockyLinux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the RLSA-2026:19350 advisory. net/url: Incorrect parsing of IPv6 host literals in net/url CVE-2026-25679 golang: internal/syscall/unix: Root.Chmod can follow symlinks out of the root...

CVE-2026-47269

pamusb provides hardware authentication for Linux using ordinary removable media. Prior to 0.9.0, pamusb's denyremote feature checks utmpx utaddrv6 to detect whether an authentication request originates from a remote session. The outer guard was if utent-utaddrv60 != 0, which only tests the first...

CVE-2026-47269

CVE-2026-47269 affects pam_usb on Linux. The deny_remote feature checks utmpx ut_addr_v6[0] to identify remote sessions, but IPv4-mapped IPv6 addresses cause the check to fail (ut_addr_v6[0] == 0, while the IPv4 address is in ut_addr_v6[3]), so remote SSH connections can be treated as local. As a...

CVE-2026-46099

A flaw was found in the Linux kernel's IPv6 networking implementation, specifically within the seg6 and rpl lwtunnels. A race condition can occur when handling destination cache entries, where a NOREF no reference destination object is used after it has been freed. This use-after-free vulnerabili...

CVE-2026-46099

The CVE-2026-46099 entry describes a use-after-free race in Linux kernel IPv6 handling for seg6 and rpl lightweight tunnels. A NOREF destination cached during ip6_route_input() can be freed by a concurrent FIB lookup on a shared nexthop under PREEMPT_RT, leading to a WARN or potential instability...

CVE-2026-45850

CVE-2026-45850 pertains to the Linux kernel vulnerability where protocol checksum validation for IPv6 could fail if there are extension headers before the IPv6 header. The confirmed fix uses iph->len as the offset to skip extension headers when performing checksum validation. Technical details...
