CVSS 7.8 · High EPSS 0,28%
Kerentanan Use After Free pada linux kernel. Skor CVSS 3.1 7.8 (High) menurut CISA ADP.
In the Linux kernel, the following vulnerability has been resolved: scsi: target: tcmu: Fix possible page UAF tcmu_try_get_data_page() looks up pages under cmdr_lock, but it does not take refcount properly and just returns page pointer. When tcmu_try_get_data_page() returns, the returned page may have been freed by tcmu_blocks_release(). We need to get_page() under cmdr_lock to avoid concurrent tcmu_blocks_release().
