| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 2024-06-19 | CVE-2021-47600 | Use After Free vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: dm btree remove: fix use after free in rebalance_children() Move dm_tm_unlock() after dm_tm_dec(). | 7.8 |
| 2024-06-19 | CVE-2021-47602 | Access of Uninitialized Pointer vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: mac80211: track only QoS data frames for admission control For admission control, obviously all of that only works for QoS data frames, otherwise we cannot even access the QoS field in the header. Syzbot reported (see below) an uninitialized value here due to a status of a non-QoS nullfunc packet, which isn't even long enough to contain the QoS header. Fix this to only do anything for QoS data packets. | 5.5 |
| 2024-06-19 | CVE-2021-47606 | Divide By Zero vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: net: netlink: af_netlink: Prevent empty skb by adding a check on len. Adding a check on len parameter to avoid empty skb. | 5.5 |
