Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (8.16%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
The eisa_eeprom_read function in the parisc isa-eeprom component (drivers/parisc/eisa_eeprom.c) in the Linux kernel before 2.6.31-rc6 allows local users to access restricted memory via a negative ppos argument, which bypasses a check that assumes that ppos is positive and causes an out-of-bounds read in the readb function.
