| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 2024-02-28 | CVE-2021-47015 | Unspecified vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: bnxt_en: Fix RX consumer index logic in the error path. In bnxt_rx_pkt(), the RX buffers are expected to complete in order. If the RX consumer index indicates an out of order buffer completion, it means we are hitting a hardware bug and the driver will abort all remaining RX packets and reset the RX ring. | 5.5 |
| 2024-02-28 | CVE-2021-47017 | Use After Free vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: ath10k: Fix a use after free in ath10k_htc_send_bundle In ath10k_htc_send_bundle, the bundle_skb could be freed by dev_kfree_skb_any(bundle_skb). | 7.8 |
| 2024-02-28 | CVE-2021-47018 | Unspecified vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: powerpc/64: Fix the definition of the fixmap area At the time being, the fixmap area is defined at the top of the address space or just below KASAN. This definition is not valid for PPC64. For PPC64, use the top of the I/O space. Because of circular dependencies, it is not possible to include asm/fixmap.h in asm/book3s/64/pgtable.h , so define a fixed size AREA at the top of the I/O space for fixmap and ensure during build that the size is big enough. | 5.5 |
| 2024-02-28 | CVE-2021-47019 | Unspecified vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: mt76: mt7921: fix possible invalid register access Disable the interrupt and synchronze for the pending irq handlers to ensure the irq tasklet is not being scheduled after the suspend to avoid the possible invalid register access acts when the host pcie controller is suspended.
