CVE-2020-11609

A flaw was found in the way the stv06xx driver in the Linux kernel handled certain types of USB descriptors. This flaw allows an attacker with the ability to induce the error conditions to crash the system. Mitigation In order to mitigate this issue it is possible to prevent the affected code fro...

CVE-2020-12654

A flaw was found in the Linux kernel. The Marvell mwifiex driver allows a remote WiFi access point to trigger a heap-based memory buffer overflow due to an incorrect memcpy operation. The highest threat from this vulnerability is to data integrity and system availability. Mitigation In order to...

CVE-2020-12653

A flaw was found in the way the mwifiexcmdappendvsietlv in Linux kernel's Marvell WiFi-Ex driver handled vendor specific information elements. A local user could use this flaw to escalate their privileges on the system. Mitigation In order to mitigate this issue it is possible to prevent the...

CVE-2020-12465

A memory overflow and data corruption flaw were found in the Mediatek MT76 driver module for WiFi in mt76addfragment in drivers/net/wireless/mediatek/mt76/dma.c. An oversized packet with too many rx fragments causes an overflow and corruption in memory of adjacent pages. A local attacker with a...

Design/Logic Flaw

gssmechfree in net/sunrpc/authgss/gssmechswitch.c in the rpcsecgsskrb5 implementation in the Linux kernel through 5.6.10 lacks certain domainrelease calls, leading to a memory leak.
