Linux kernel 安全漏洞

Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. A security vulnerability exists in the Linux kernel that originates from a device being exposed to the USB subsystem before the ath9k driver initialization is complete...

CVE-2021-47169

In the Linux kernel, the following vulnerability has been resolved: serial: rp2: use 'requestfirmware' instead of 'requestfirmwarenowait' In 'rp2probe', the driver registers 'rp2uartinterrupt' then calls 'rp2fwcb' through 'requestfirmwarenowait'. In 'rp2fwcb', if the firmware don't exists, functi...

kernel: tpm: tpm_tis: Add the missed acpi_put_table() to fix memory leak

A memory leak flaw was found in the Linux kernel's TPM TIS driver. The checkacpitpm2 function retrieves the TPM2 ACPI table to verify its presence but fails to release the table reference via acpiputtable, resulting in a memory leak each time the function is called during driver initialization...

kernel: drm: Prevent drm_copy_field() to attempt copying a NULL pointer

A NULL pointer dereference flaw was found in the Linux kernel's DRM subsystem. When a graphics driver incorrectly fails to initialize required fields in the drmdriver structure, the drmcopyfield function attempts to copy from a NULL pointer when handling the DRMIOCTLVERSION ioctl, causing a kerne...

kernel: ALSA: ymfpci: Fix BUG_ON in probe function

An assertion failure was found in the Linux kernel's Yamaha YMF sound card driver during buffer validation. The probe function includes a BUGON assertion that compares DMA buffer sizes without accounting for alignment, causing the assertion to fail when the aligned buffer size doesn't exactly mat...

kernel: perf/smmuv3: Fix hotplug callback leak in arm_smmu_pmu_init()

A resource-handling flaw was found in the Linux kernel performance monitoring driver for ARM System Memory Management Unit version 3 in the way hotplug callbacks are registered during driver initialization. If driver registration fails, previously added CPU hotplug callbacks are not removed,...

CVE-2020-1792

Honor V10 smartphones with versions earlier than BKL-AL20 10.0.0.156C00E156R2P4 and versions earlier than BKL-L09 10.0.0.146C432E4R1P4 have an out of bounds write vulnerability. The software writes data past the end of the intended buffer because of insufficient validation of certain parameter wh...

kernel: null pointer dereference in drivers/net/ethernet/intel/fm10k/fm10k_main.c

A flaw was found in the way the fm10k driver in the Linux kernel reacted to memory-related errors during driver initialization. This flaw allows a local attacker to cause a denial of service and crash the system...

Monitoring Windows Console Activity (Part 2)

This is the second of two blogs that discuss the implementation of the Windows console architecture from years past, with a primary focus on the current implementation present on modern versions of Windows. Read our first blog, "Monitoring Windows Console Activity Part 1," for more. Capturing the...
