Oracle Linux: CVE-2020-9383: ELSA-2020-5663: Unbreakable Enterprise kernel security update (IMPORTANT) (Multiple Advisories)
Description
An issue was discovered in the Linux kernel 3.16 through 5.5.6. set_fdc in drivers/block/floppy.c leads to a wait_til_ready out-of-bounds read because the FDC index is not checked for errors before assigning it, aka CID-2e90ca68b0d2. An out-of-bounds (OOB) memory access flaw was found in the floppy driver module in the Linux kernel. A bounds check failure allows a local attacker to gain access to out-of-bounds memory leading to a system crash or a leak of internal kernel information. The highest threat from this vulnerability is to system availability.
