CVE-2026-23209 1 Linux 1 Linux Kernel 2026-04-16 7.8 High
In the Linux kernel, the following vulnerability has been resolved: macvlan: fix error recovery in macvlan_common_newlink() valis provided a nice repro to crash the kernel: ip link add p1 type veth peer p2 ip link set address 00:00:00:00:00:20 dev p1 ip link set up dev p1 ip link set up dev p2 ip link add mv0 link p2 type macvlan mode source ip link add invalid% link p2 type macvlan mode source macaddr add 00:00:00:00:00:20 ping -c1 -I p1 1.2.3.4 He also gave a very detailed analysis: <quote valis> The issue is triggered when a new macvlan link is created with MACVLAN_MODE_SOURCE mode and MACVLAN_MACADDR_ADD (or MACVLAN_MACADDR_SET) parameter, lower device already has a macvlan port and register_netdevice() called from macvlan_common_newlink() fails (e.g. because of the invalid link name). In this case macvlan_hash_add_source is called from macvlan_change_sources() / macvlan_common_newlink(): This adds a reference to vlan to the port's vlan_source_hash using macvlan_source_entry. vlan is a pointer to the priv data of the link that is being created. When register_netdevice() fails, the error is returned from macvlan_newlink() to rtnl_newlink_create(): if (ops->newlink) err = ops->newlink(dev, &params, extack); else err = register_netdevice(dev); if (err < 0) { free_netdev(dev); goto out; } and free_netdev() is called, causing a kvfree() on the struct net_device that is still referenced in the source entry attached to the lower device's macvlan port. Now all packets sent on the macvlan port with a matching source mac address will trigger a use-after-free in macvlan_forward_source(). </quote valis> With all that, my fix is to make sure we call macvlan_flush_sources() regardless of @create value whenever "goto destroy_macvlan_port;" path is taken. Many thanks to valis for following up on this issue.

CVE-2002-2254 1 Linux 1 Linux Kernel 2026-04-16 N/A
The experimental IP packet queuing feature in Netfilter / IPTables in Linux kernel 2.4 up to 2.4.19 and 2.5 up to 2.5.31, when a privileged process exits and network traffic is not being queued, may allow a later process with the same Process ID (PID) to access certain network traffic that would otherwise be restricted.
CVE-2001-1392 2 Linux, Redhat 2 Linux Kernel, Linux 2026-04-16 N/A
The Linux kernel before 2.2.19 does not have unregister calls for (1) CPUID and (2) MSR drivers, which could cause a DoS (crash) by unloading and reloading the drivers.

The MAC module in Netfilter in Linux kernel 2.4.1 through 2.4.11, when configured to filter based on MAC addresses, allows remote attackers to bypass packet filters via small packets.
CVE-1999-0781 3 Freebsd, Kde, Linux 3 Freebsd, Kde, Linux Kernel 2026-04-16 N/A
KDE allows local users to execute arbitrary commands by setting the KDEDIR environmental variable to modify the search path that KDE uses to locate its executables.
CVE-2004-1056 3 Linux, Redhat, Ubuntu 3 Linux Kernel, Enterprise Linux, Ubuntu Linux 2026-04-16 N/A
Direct Rendering Manager (DRM) driver in Linux kernel 2.6 does not properly check the DMA lock, which could allow remote attackers or local users to cause a denial of service (X Server crash) and possibly modify the video output.
CVE-2003-1423 4 Linux, Microsoft, Petitforum and 1 more 4 Linux Kernel, All Windows, Petitforum and 1 more 2026-04-16 N/A
Petitforum stores the liste.txt data file under the web document root with insufficient access control, which allows remote attackers to obtain sensitive information such as e-mail addresses and encrypted passwords.
CVE-1999-0451 1 Linux 1 Linux Kernel 2026-04-16 N/A

CVE-2006-2936 2 Linux, Redhat 2 Linux Kernel, Enterprise Linux 2026-04-16 N/A
The ftdi_sio driver (usb/serial/ftdi_sio.c) in Linux kernel 2.6.x up to 2.6.17, and possibly later versions, allows local users to cause a denial of service (memory consumption) by writing more data to the serial port than the hardware can handle, which causes the data to be queued.
