In the Linux kernel, the following vulnerability has been resolved: mtd: require write permissions for locking and badblock ioctls MEMLOCK, MEMUNLOCK and OTPLOCK modify protection bits. Thus require write permission. Depending on the hardware MEMLOCK might even be write-once, e.g. for SPI-NOR...

CVE-2021-46959 spi: Fix use-after-free with devm_spi_alloc_*

In the Linux kernel, the following vulnerability has been resolved: spi: Fix use-after-free with devmspialloc We can't rely on the contents of the devres list during spiunregistercontroller, as the list is already torn down at the time we perform devresfind for devmspireleasecontroller. This caus...

CVE-2021-46959

CVE-2021-46959 is a Linux kernel SPI subsystem use-after-free issue (devm_spi_alloc_{master,slave}) caused by relying on the devres list during spi_unregister_controller. The root cause is that devres_find() runs after the devres list has been torn down, leading to underflow of reference counters...

How To Hunt For UEFI Malware Using Velociraptor

UEFI threats have historically been limited in number and mostly implemented by nation state actors as stealthy persistence. However, the recent proliferation of Black Lotus on the dark web, Trickbot enumeration module late 2022, and Glupteba November 2023 indicates that this historical trend may...
