DEBIAN-CVE-2026-74676

In the Linux kernel, the following vulnerability has been resolved: vt: add permission check for KDSKBMETA ioctl KDSKBMETA modifies keyboard meta mode but lacks the !perm check that all other keyboard setter ioctls in vtkioctl enforce, allowing a process to change meta mode on a non-controlling...

DEBIAN-CVE-2026-74675

In the Linux kernel, the following vulnerability has been resolved: vt: stabilize tty reference in kbdkeycode with ttyportttyget kbdkeycode reads vc-port.tty without acquiring a tty reference, racing against conshutdown which clears port.tty under a different lock. Use ttyportttyget/ttykrefput to...

In the Linux kernel, the following vulnerability has been resolved: net: usb: ipheth: fix carrierwork UAF on disconnect iphethsndbulkcallback re-arms the carrier-check work on any non-zero URB status: else scheduledelayedwork&dev-carrierwork, 0; Nothing ties that to the interface being up, so the...

DEBIAN-CVE-2026-74673

In the Linux kernel, the following vulnerability has been resolved: Input: evdev - fix information leak in evdevpassvalues In evdevpassvalues, the inputevent structure is allocated on the kernel stack and populated field-by-field. However, it is never fully initialized. On architectures where...

DEBIAN-CVE-2026-74678

In the Linux kernel, the following vulnerability has been resolved: net: usb: ax88179178a: fix skb leak in ax88179txfixup When the interface has NETIFFSG enabled and skblinearize fails in ax88179txfixup, the function returns NULL without freeing the skb. usbnetstartxmit treats a NULL return from...

DEBIAN-CVE-2026-74674

In the Linux kernel, the following vulnerability has been resolved: mm: fix incorrect flush address in direct page table reclaim When zappterange reclaims a page table, it does: ptefreetlbtlb, pmdpgtablepmdval, addr; and this is unconditionally wrong: if this code executes, addr always points one...

DEBIAN-CVE-2026-74671

In the Linux kernel, the following vulnerability has been resolved: ima: fix out-of-bounds read in xattrverify The digest-length check in xattrverify mixes int and sizet: if xattrlen - sizeofxattrvalue-type - hashstart = iint-imahash-length sizeof yields sizet, so the usual arithmetic conversions...

DEBIAN-CVE-2026-74663

In the Linux kernel, the following vulnerability has been resolved: net/sched: reject overly deep qdisc hierarchies Deep qdisc hierarchies can lead to excessive recursion in qdisc tree walkers and exhaust the kernel stack. The existing loop check does not cover the create-and-graft path, so a...

DEBIAN-CVE-2026-74669

In the Linux kernel, the following vulnerability has been resolved: ipvs: clear IPv4 options after rebasing tunnel ICMP errors ipvsinicmp rebases an skb from the outer ICMP packet to the quoted original request before passing it to icmpsend. However, IPCBskb-opt still describes the outer IPv4...

DEBIAN-CVE-2026-74668

In the Linux kernel, the following vulnerability has been resolved: packet: use consistent hardheaderlen in TXRING send path tpacketsnd reads dev-hardheaderlen independently for skb allocation and header construction in tpacketfillskb. Concurrent netdevice reconfiguration can therefore make the...

DEBIAN-CVE-2026-74664

In the Linux kernel, the following vulnerability has been resolved: net: openvswitch: reallocate update replies for mismatched IDs ovsflowcmdnew preallocates the optional reply skb before it takes ovsmutex and before it knows which existing flow will be updated. That is normally fine because the...

DEBIAN-CVE-2026-74665

In the Linux kernel, the following vulnerability has been resolved: net: fix skb length accounting after generic XDP frag adjustment Generic XDP exposes non-linear skb fragments through an xdpbuff. If an XDP program adjusts the fragment area, bpfprogrungenericxdp copies xdpfragssize back to...

DEBIAN-CVE-2026-74670
