Last modified
CVE-2021-29264 is a medium-severity vulnerability rated 5.5/10 on the CVSS scale. An issue was discovered in the Linux kernel through 5.11.10. drivers/net/ethernet/freescale/gianfar.c in the Freescale Gianfar Ethernet driver allows attackers to cause a system crash because a negative fragment size is calculated in situations involving an rx queue overrun when jumbo packets are used and NAPI is enabled, aka CID-d8861bab48b6.. EPSS estimates a 0.27% chance of exploitation in the next 30 days.
