Overview
What is CVE-2026-90267?
In the Linux kernel, the following vulnerability has been resolved:
scsi: sd: Fix special_vec mempool leak when scsi_alloc_sgtables() fails
sd_set_special_bvec() allocates a special payload page for UNMAP and WRITE SAME commands. If scsi_alloc_sgtables() fails afterward in sd_setup_unmap_cmnd() or sd_setup_write_same{10,16}_cmnd(), the SCSI midlayer does not call uninit_command() because RQF_DONTPREP is not set yet, leaking the page.
Call sd_uninit_command() on error, and clear RQF_SPECIAL_PAYLOAD after freeing the page.
