pnpm: Manifest identity spoof satisfies allowBuilds and runs attacker lifecycle

Summary Keep build approval for opaque dependency sources byte-exact for GHSA-5wx6-mg75-v57r / CAND-PNPM-123. Merged upstream commit bf1b731ee6 fixed the original name-only approval bypass by making build policy consume the resolved dependency identity. One collision remained: the generic...

DEBIAN-CVE-2026-53307

In the Linux kernel, the following vulnerability has been resolved: pinctrl: pinconf-generic: Fully validate 'pinmux' property The pinconfgenericparsedtpinmux assumes that the 'pinmux' property is not empty when present. This might be not true. With that, the allocator will give a special value i...

CVE-2026-53295

In the Linux kernel, the following vulnerability has been resolved: mailbox: add sanity check for channel array Fail gracefully if there is no channel array attached to the mailbox controller. Otherwise the later dereference will cause an OOPS which might not be seen because mailbox controllers...

DEBIAN-CVE-2026-53296

In the Linux kernel, the following vulnerability has been resolved: mailbox: mailbox-test: free channels on probe error On probe error, free the previously obtained channels. This not only prevents a leak, but also UAF scenarios because the client structure will be removed nonetheless because it...

CVE-2026-53322 vfio/pci: Clean up DMABUFs before disabling function

In the Linux kernel, the following vulnerability has been resolved: vfio/pci: Clean up DMABUFs before disabling function On device shutdown, make vfiopcicoreclosedevice call vfiopcidmabufcleanup before the function is disabled via vfiopcicoredisable. This ensures that all access via DMABUFs is...
