kernel: drm/amdgpu: prevent NULL pointer dereference if ATIF is not supported

A flaw was found in the Linux kernel's AMD GPU driver. A failure to properly handle error returns during ACPI Advanced Configuration and Power Interface object evaluation can result in a NULL pointer dereference when specific interface features are unsupported. A local user could exploit this fla...

kernel: ACPI: sysfs: validate return type of _STR method

A flaw was found in the Linux kernel. This vulnerability occurs in the ACPI Advanced Configuration and Power Interface system file system sysfs when processing the STR method. If a non-buffer object is returned, the system attempts to access invalid memory. A local attacker could exploit this to...

kernel: ACPICA: check null return of ACPI_ALLOCATE_ZEROED() in acpi_db_convert_to_package()

A flaw was found in the Linux kernel's Advanced Configuration and Power Interface ACPI Component Architecture ACPICA. A missing check for a null return value from a memory allocation function ACPIALLOCATEZEROED in the acpidbconverttopackage function can lead to a null pointer dereference. This...

kernel: ACPI: PAD: fix crash in exit_round_robin()

In the Linux kernel, the following vulnerability has been resolved: ACPI: PAD: fix crash in exitroundrobin The kernel occasionally crashes in cpumaskclearcpu, which is called within exitroundrobin, because when executing clearbitnr, addr with nr set to 0xffffffff, the address calculation may caus...

kernel: arm64: acpi: Harden get_cpu_for_acpi_id() against missing CPU entry

A flaw was found in the Linux kernel, specifically within the ACPI Advanced Configuration and Power Interface CPU hotplug functionality. This vulnerability occurs when the system attempts to retrieve CPU information, and a missing CPU entry can lead to a NULL pointer dereference. A local attacker...

In the Linux kernel, the following vulnerability has been resolved: irqchip/gic-v2m: Prevent use after free of gicv2mgetfwnode With ACPI in place, gicv2mgetfwnode is registered with the pci subsystem as pcimsigetfwnodecb, which may get invoked at runtime during a PCI host bridge probe. But, the...

Vulnerability of the acpi_device_add() function in the drivers/acpi/scan.c module – The ACPI support driver for the Linux kernel’s core, which allows attackers to access protected information.

Vulnerability of the acpideviceadd function in the drivers/acpi/scan.c module – The ACPI support driver for the Linux kernel’s processor is vulnerable to a vulnerability where improper memory release occurs before removing the last reference point memory leak. Exploiting this vulnerability could...
