In the Linux kernel, the following vulnerability has been resolved: blk-mq: fix NULL dereference on q-elevator in blkmqelvswitchnone After grabbing q-sysfslock, q-elevator may become NULL because of elevator switch. Fix the NULL dereference on q-elevator by checking it with lock...

kernel: RDMA/core: Make sure "ib_port" is valid when access sysfs node

A NULL pointer dereference flaw was found in the Linux kernel RDMA core's sysfs handling. A local user with access to InfiniBand sysfs nodes can read sysfs attributes while an InfiniBand port is being removed, causing the kernel to dereference a NULL ibport pointer when the port structure has bee...

GHSA-JQ35-85CJ-FJ4P /sys/devices/virtual/powercap accessible by default to containers

Intel's RAPL Running Average Power Limit feature, introduced by the Sandy Bridge microarchitecture, provides software insights into hardware energy consumption. To facilitate this, Intel introduced the powercap framework in Linux kernel 3.13, which reads values via relevant MSRs model specific...

The vulnerability of the read_descriptors() function in the drivers/usb/core/sysfs.c file of the Linux kernel’s USB driver allows a attacker to cause a service failure.

The vulnerability of the readdescriptors function in the drivers/usb/core/sysfs.c file of the Linux kernel’s USB driver is related to reading a reserved buffer from outside the system. Exploiting this vulnerability could allow an attacker to cause a service failure...
