The vulnerability of the `nvme_dbbuf_set()` function in the driver/nvme/host/pci.c module of the Linux NVME driver allows a attacker to escalate their privileges or execute arbitrary code.

The vulnerability of the nvmedbbufset function in the drivers/nvme/host/pci.c file of the NVME kernel driver in Linux is related to the execution of operations outside the buffer boundaries. Exploiting this vulnerability can allow an attacker to increase their privileges or execute arbitrary code...

CVE-2026-63842

A flaw was found in the Linux kernel's AMD GPU JPEG driver. This vulnerability arises from the driver's inability to properly handle 64-bit user fence writes to its JPEG rings. A local user could exploit this by submitting specially crafted commands, potentially leading to system instability or a...

CVE-2026-63837

A flaw was found in the Linux kernel's Elastic Network Adapter ENA driver. The driver's Precision Time Protocol PTP Hardware Clock PHC support, specifically the enaphcgettimex64 function, fails to check the return code of an internal timestamp retrieval function. This oversight can lead to...

CVE-2026-63832

A flaw was found in the Linux kernel's mt76 Wi-Fi driver. This vulnerability occurs due to improper handling of Wi-Fi station additions, where the driver fails to adequately verify existing client connections. A remote attacker could exploit this by manipulating Wi-Fi authentication processes,...

CVE-2026-63822

A flaw was found in the Linux kernel's ath11k Wi-Fi driver. This vulnerability, a double free, occurs when memory buffers are incorrectly released twice during the device unbinding process after an initial firmware initialization error. This can lead to system instability or a kernel crash,...

CVE-2026-64099

A flaw was found in the Linux kernel's drm/v3d graphics driver. This vulnerability, a use-after-free error, occurs in the CPU job input/output control ioctl error path. When an error is encountered, the system attempts to access memory that has already been freed, which can lead to system...

CVE-2026-39879

CVE-2026-39879 affects syslog-ng before version 4.12, where a missing sanitization in afsql_dd_run_query can allow SQL injection from an untrusted source when using the SQL destination driver (not enabled by default). The issue lies in the afsql.c component (afsql_dd_run_query) and is exploitable...

CVE-2026-39879 SQL injection in syslog-ng SQL destionation driver

Due to a missing sanitization call in afsqlddrunquery, syslog-ng before 4.12 are vulnerable to SQL injection from an untrusted source. This is not part of the default configuration, the SQL driver has to be manually configured. Fixes are in syslog-ng 4.12, syslog-ng Premium Edition 8.2 and...

CVE-2026-39879 SQL injection in syslog-ng SQL destionation driver

Due to a missing sanitization call in afsqlddrunquery, syslog-ng before 4.12 are vulnerable to SQL injection from an untrusted source. This is not part of the default configuration, the SQL driver has to be manually configured. Fixes are in syslog-ng 4.12, syslog-ng Premium Edition 8.2 and...

CVE-2026-64191 i2c: stub: Reject I2C block transfers with invalid length

In the Linux kernel, the following vulnerability has been resolved: i2c: stub: Reject I2C block transfers with invalid length The I2CSMBUSI2CBLOCKDATA case in stubxfer uses data-block0 as the transfer length. The existing check only clamps it to avoid overrunning the chip-words256 register array,...

CVE-2026-64191

The CVE-2026-64191 issue affects the Linux kernel i2c-stub driver (CONFIG_I2C_STUB=m) where I2C_SMBUS_I2C_BLOCK_DATA did not validate data->block[0] against I2C_SMBUS_BLOCK_MAX, allowing out-of-bounds access when an I2C_SMBUS_IOCTL with a block length > 32 is issued. The bug contrasts with ...

CVE-2026-64190 net: team: fix NULL pointer dereference in team_xmit during mode change

In the Linux kernel, the following vulnerability has been resolved: net: team: fix NULL pointer dereference in teamxmit during mode change teamchangemode clears team-ops with memset before restoring safe dummy handlers via teamadjustops. A concurrent teamxmit running under RCU on another CPU can...

CVE-2026-64168

A flaw was found in the Linux kernel's spi-sprd driver. This vulnerability occurs when the driver attempts to release Direct Memory Access DMA channels after a DMA setup failure during the probe phase. Without properly checking if DMA is enabled, the driver may try to dereference an invalid point...

CVE-2026-64113

A flaw was found in the Linux kernel's ixgbevf network driver. This vulnerability, a use-after-free, occurs when the driver attempts to process network packets for a specific multicast workaround. An attacker could potentially exploit this by sending specially crafted network traffic, which may...

CVE-2026-53387

A flaw was found in the Linux kernel's veml6075 light sensor driver. The driver performs an out-of-bounds array access when processing certain index values from the VEML6075CONFIT register. This issue could potentially lead to system instability or a denial of service if triggered by a faulty...

CVE-2026-53384

A flaw was found in the Linux kernel's 8250dw serial driver. When the clknotifierregister function fails during the probe process, the 8250 port is not properly unregistered. This oversight can lead to a use-after-free vulnerability, where previously freed memory is still referenced. An attacker...
