CVE-2026-99087: Linux

Описание

Оригинално описание

In the Linux kernel, the following vulnerability has been resolved: dm-integrity: fix NULL pointer dereference when the 'R' flag is used If the dm-integrity device has the SB_FLAG_DIRTY_BITMAP flag set and the user activates the device in the 'R' mode, a crash in dm_integrity_resume happens because the function attempts to read the journal containing the bitmap. This patch makes dm-integrity skip any writes to the device in dm_integrity_resume if the device is activated in the 'R' mode.
