CVE-2022-50044

CVE-2022-50044 stems from a race in the Linux kernel’s net: qrtr MHI channel handling. After enabling, an MHI event/interrupt can occur either before dev_set_drvdata is completed (causing qrtr-ns to fail service enumeration) or after dev_set_drvdata but before qrtr_endpoint_register (potential ke...

CVE-2022-50023 dmaengine: dw-axi-dmac: ignore interrupt if no descriptor

In the Linux kernel, the following vulnerability has been resolved: dmaengine: dw-axi-dmac: ignore interrupt if no descriptor If the channel has no descriptor and the interrupt is raised then the kernel will OOPS. Check the result of vchannextdesc in the handler axichanblockxfercomplete to avoid...

CVE-2022-50023

The CVE-2022-50023 issue affects the Linux kernel's DMAengine dw-axi-dmac component. When a channel has no descriptor and an interrupt is raised, the kernel can OOPS. The root cause is not validating the descriptor result; the fix is to check the outcome of vchan_next_desc() in axi_chan_block_xfe...

CVE-2022-49942 wifi: mac80211: Don't finalize CSA in IBSS mode if state is disconnected

In the Linux kernel, the following vulnerability has been resolved: wifi: mac80211: Don't finalize CSA in IBSS mode if state is disconnected When we are not connected to a channel, sending channel "switch" announcement doesn't make any sense. The BSS list is empty in that case. This causes the fo...

CVE-2025-38042

CVE-2025-38042 concerns the Linux kernel DMA engine for TI k3-udma-glue. The issue stems from relying on the skip_fdq argument in k3_udma_glue_reset_rx_chn(); on some platforms there is a single FDQ for all RX flows, while others have a separate FDQ per flow. The fix infers FDQ behavior from the ...

CVE-2025-27587

OpenSSL 3.0.0 through 3.3.2 on the PowerPC architecture is vulnerable to a Minerva attack, exploitable by measuring the time of signing of random messages using the EVPDigestSign API, and then using the private key to extract the K value nonce from the signatures. Next, based on the bit size of t...

Sudoku: Decomposing DRAM Address Mapping into Component Functions

Decomposing DRAM address mappings into component-level functions is critical for understanding memory behavior and enabling precise RowHammer attacks, yet existing reverse-engineering methods fall short. We introduce novel timing-based techniques leveraging DRAM refresh intervals and consecutive...

FARFETCH'D: a Side-Channel Analysis Framework for Privacy Applications on Confidential Virtual Machines

Confidential virtual machines CVMs based on trusted execution environments TEEs enable new privacy-preserving solutions. Yet, they leave side-channel leakage outside their threat model, shifting the responsibility of mitigating such attacks to developers. However, mitigations are either not gener...
