UBUNTU-CVE-2026-64509

In the Linux kernel, the following vulnerability has been resolved: rust: block: fix GenDisk cleanup paths GenDiskBuilder::build still has fallible work after blkmqallocdisk, but its error path only recovers the foreign queue data. That leaks the temporary gendisk and requestqueue until later...

CVE-2026-64509

The CVE fixes a leak in the Linux kernel rust: block GenDisk cleanup paths. GenDiskBuilder::build() leaves fallible work after __blk_mq_alloc_disk() that can cause the temporary gendisk and request_queue to be retained until teardown, if the caller moves the last Arc<TagSet> into build(). T...

SUSE CVE-2026-45997

In the Linux kernel, the following vulnerability has been resolved: scsi: sd: fix missing putdisk when deviceadd&diskdev fails If deviceadd&sdkp-diskdev fails, putdevice runs scsidiskrelease, which frees the scsidisk but leaves the gendisk referenced. The deviceadddisk error path in sdprobe calls...

CVE-2026-45997

A flaw was found in the Linux kernel's SCSI disk sd driver. When adding a new device, a failure in deviceadd can lead to a resource leak where a gendisk remains referenced but is not properly freed. This missing cleanup, specifically the putdisk call, can result in resource exhaustion. A local...
