radareorg/radare2: Out-of-bounds Read
CVE-2022-1296 is a critical-severity out-of-bounds read vulnerability in radareorg/radare2 from Radareorg, with a CVSS 3.1 base score of 9.1 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. The record lists version 5.6.8 as the first without the flaw, so updating radareorg/radare2 to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.78% chance of exploitation within 30 days, higher than 56% of scored CVEs.
