Page history
Changes are dated when recorded; day views use the last saved version from that UTC day, and citations stay fixed.
CISA KEV is observed exploitation evidence. FIRST EPSS is a dated prediction of exploitation in the next 30 days. Missing scores are unknown. This collector requests predictions only for explicit CVE aliases in the public NuGet archive; Microsoft release views retain their existing prediction scope.
No collected risk observation for these identifiers. This does not establish absence of exploitation or a zero probability.

nvmet-fc: fix invalid free in LS IOD error path
In the Linux kernel, the following vulnerability has been resolved:
nvmet-fc: fix invalid free in LS IOD error path
nvmet_fc_alloc_ls_iodlist() advances iod while initializing the LS IOD
array. If an rqstbuf allocation or response buffer DMA mapping fails,
the unwind loop decrements iod past the start of the array. The final
kfree(iod) therefore frees an address before the allocated object.
This can be reproduced with nvme-fcloop and failslab by setting
fail-nth to 6 before creating a target port. KASAN reports:
BUG: KASAN: invalid-free in nvmet_fc_register_targetport
Free of addr ffff88816cf8ff48 by task nvmet_fail_nth/9552
Free the original allocation base stored in tgtport->iod instead. With
this fix applied, the same sysfs write with fail-nth=6 returns -ENOMEM
without any KASAN report.
