  "title": "nvmet: pci-epf: reject too-short SGL segments",
  "description": "In the Linux kernel, the following vulnerability has been resolved:  nvmet: pci-epf: reject too-short SGL segments  The host controls an SGL segment\u0027s length. A nonzero length smaller than one SGL descriptor makes nr_descs zero, so nvmet_pci_epf_get_sgl_segment() reads the type byte of sgls[-1] outside the allocated buffer. If that byte contains a segment descriptor type, the function also copies the preceding 16 bytes and returns a negative descriptor count.  The read was reproduced in 3/3 KASAN boots with only the host transfer mocked by a KUnit test:    BUG: KASAN: slab-out-of-bounds in nvmet_pci_epf_get_sgl_segment   Read of size 1 by task kunit_try_catch   Call Trace:    nvmet_pci_epf_get_sgl_segment    nvmet_pci_epf_short_sgl_test   Kernel panic - not syncing: KASAN: panic_on_warn set ...  Reject segments that cannot hold one descriptor before allocating or transferring their contents.",
