CVE-2026-89953

CVE-2026-89953 is a memory leak in the Linux kernel's mtdoops module. The root cause is that mtdoops_notify_remove() detaches from the backing MTD device but leaves the oops_page_used bitmap allocated. When the same MTD device is subsequently re-registered, the add path allocates a new bitmap and...

CVE-2026-89953: Undefined Security Weakness

In the Linux kernel, the following vulnerability has been resolved: mtd: mtdoops: free page bitmap when the backing MTD is removed mtdoopsnotifyadd allocates oopspageused when the configured MTD device is registered. mtdoopsnotifyremove detaches from that device but leaves the bitmap allocated. I...
