CVE-2026-68130

In the Linux kernel, the following vulnerability has been resolved: ksmbd: defer destroyprevioussession until after NTLM authentication In ntlmauthenticate, destroyprevioussession is called using a user pointer resolved from the client-supplied NTLM blob username field before the NTLMv2 response ...

CVE-2026-68119

In the Linux kernel, the following vulnerability has been resolved: tcp: initialize standalone TCP-AO response padding tcpv4sendack and tcpv6sendresponse construct standalone TCP responses with TCP-AO options. The option length carries the actual MAC length, but the TCP header length includes the...

CVE-2026-68424 mtd: virt_concat: fix use-after-free in mtd_virt_concat_destroy_joins()

In the Linux kernel, the following vulnerability has been resolved: mtd: virtconcat: fix use-after-free in mtdvirtconcatdestroyjoins mtdconcatdestroy frees item-concat so calling mtdvirtconcatputmtddevicesitem-concat leads to a use after free. Fix this by moving mtdvirtconcatputmtddevices before...

CVE-2026-68424

CVE-2026-68424 affects the Linux kernel MTD virt_concat code. The root cause is a use-after-free: mtd_concat_destroy() frees item->concat, so calling mtd_virt_concat_put_mtd_devices(item->concat) can use freed memory. The fix migrates the call to mtd_virt_concat_put_mtd_devices() to occur b...

CVE-2026-68423 mtd: virt_concat: fix use-after-free in mtd_virt_concat_destroy()

In the Linux kernel, the following vulnerability has been resolved: mtd: virtconcat: fix use-after-free in mtdvirtconcatdestroy mtdconcatdestroy frees item-concat so calling mtdvirtconcatputmtddevicesitem-concat after that leads to a use-after-free. Fix it by moving mtdvirtconcatputmtddevices...

CVE-2026-68423

The vulnerability CVE-2026-68423 concerns the Linux kernel’s MTD subsystem, specifically the virt_concat code path. A use-after-free occurs in mtd_virt_concat_destroy() because mtd_concat_destroy() frees item->concat, after which mtd_virt_concat_put_mtd_devices(item->concat) may be invoked,...

CVE-2026-68375 bnxt_en: Handle partially initialized auxiliary devices

In the Linux kernel, the following vulnerability has been resolved: bnxten: Handle partially initialized auxiliary devices bnxtauxdevicesinit calls auxiliarydeviceinit before all fields used by bnxtauxdevrelease are initialized. After auxiliarydeviceinit succeeds, later errors must unwind with...

CVE-2026-68375

The CVE affects bnxt_en in the Linux kernel. bnxt_aux_devices_init() calls auxiliary_device_init() before all fields used by bnxt_aux_dev_release() are initialized. If allocation fails after auxiliary_device_init(), the release path can dereference or clear partially initialized state. The fix is...
