CVE-2024-40904 — USB: class: cdc-wdm: Fix CPU lockup caused by excessive log messages

Affected: Linux

In the Linux kernel, the following vulnerability has been resolved:

USB: class: cdc-wdm: Fix CPU lockup caused by excessive log messages

The syzbot fuzzer found that the interrupt-URB completion callback in the cdc-wdm driver was taking too long, and the driver's immediate resubmission of interrupt URBs with -EPROTO status combined with the dummy-hcd emulation to cause a CPU lockup:

cdc_wdm 1-1:1.0: nonzero urb status received: -71 cdc_wdm 1-1:1.0: wdm_int_callback - 0 bytes watchdog: BUG: soft lockup - CPU#0 stuck for 26s!

Chenyuan Yang discovered that the CEC driver driver in the Linux kernel contained a use-after-free vulnerability. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2024-23848)

It was discovered that the JFS file system contained an out-of-bounds read vulnerability when printing xattr debug information. A local attacker could use this to cause a denial of service (system crash). (CVE-2024-40902)

Several security issues were discovered in the Linux kernel. An attacker could possibly use these to compromise the system. This update corrects flaws in the following subsystems: - ARM64 architecture; - MIPS architecture; - PA-RISC architecture; - PowerPC architecture; - RISC-V architecture; - x86 architecture; - Block layer subsystem; - ACPI drivers; - Drivers core; - Null block device driver; - Character device driver; - TPM device driver; - Clock framework and drivers; - CPU frequency scaling framework; - Hardware crypto device drivers; - CXL (Compute Express Link) drivers; - Buffer Sharing and Synchronization framework; - DMA engine subsystem; - EFI core; - FPGA Framework; - GPU drivers; - Greybus drivers; - HID subsystem; - HW tracing; - I2C subsystem; - IIO subsystem; - InfiniBand drivers; - Input Device (Mouse) drivers; - Mailbox framework; - Media drivers; - Microchip PCI driver; - VMware VMCI Driver; - Network drivers; - PCI subsystem; -…
