CVE-2026-98724

Sin historial EPSS suficiente todavía.

In the Linux kernel, the following vulnerability has been resolved: nvmet: pci-epf: reject too-short SGL segments The host controls an SGL segment's 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.
