"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nnvmet: pci-epf: reject too-short SGL segments\n\nThe host controls an SGL segment's length. A nonzero length smaller than\none SGL descriptor makes nr_descs zero, so\nnvmet_pci_epf_get_sgl_segment() reads the type byte of sgls[-1] outside\nthe allocated buffer. If that byte contains a segment descriptor type,\nthe function also copies the preceding 16 bytes and returns a negative\ndescriptor count.\n\nThe read was reproduced in 3/3 KASAN boots with only the host transfer\nmocked by a KUnit test:\n\n BUG: KASAN: slab-out-of-bounds in nvmet_pci_epf_get_sgl_segment\n Read of size 1 by task kunit_try_catch\n Call Trace:\n nvmet_pci_epf_get_sgl_segment\n nvmet_pci_epf_short_sgl_test\n Kernel panic - not syncing: KASAN: panic_on_warn set ...\n\nReject segments that cannot hold one descriptor before allocating or\ntransferring their contents."
