In the Linux kernel, the following vulnerability has been resolved: scsi: target: Fix NULL pointer dereference in corescsi3decodespeciport() The function corescsi3decodespeciport(), in its error code path, unconditionally calls corescsi3lunaclundependitem() passing the destsedeve pointer, which may be NULL. This can lead to a NULL pointer dereference if destsedeve remains unset. SPC-3 PR SPECIPT: Unable to locate desttpg Unable to handle kernel paging request at virtual address dfff800000000012 Call trace: corescsi3lunaclundependitem+0x2c/0xf0 [targetcoremod] (P) corescsi3decodespeciport+0x120c/0x1c30 [targetcoremod] corescsi3emulateproregister+0x6b8/0xcd8 [targetcoremod] targetscsi3emulateprout+0x56c/0x840 [targetcoremod] Fix this by adding a NULL check before calling corescsi3lunaclundependitem()
