CVE-2021-47374 – dma-debug: prevent an error message from causing runtime problems
https://notcve.org/view.php?id=CVE-2021-47374
21 May 2024 — In the Linux kernel, the following vulnerability has been resolved: dma-debug: prevent an error message from causing runtime problems For some drivers, that use the DMA API. This error message can be reached several millions of times per second, causing spam to the kernel's printk buffer and bringing the CPU usage up to 100% (so, it should be rate limited). However, since there is at least one driver that is in the mainline and suffers from the error condition, it is more useful to err_printk() here instead... • https://git.kernel.org/stable/c/de4afec2d2946c92c62a15ab341c70b287289e6a •
CVE-2021-47373 – irqchip/gic-v3-its: Fix potential VPE leak on error

21 May 2024 — In the Linux kernel, the following vulnerability has been resolved: irqchip/gic-v3-its: Fix potential VPE leak on error In its_vpe_irq_domain_alloc, when its_vpe_init() returns an error, there is an off-by-one in the number of VPEs to be freed. Fix it by simply passing the number of VPEs allocated, which is the index of the loop iterating over the VPEs.

CVE-2021-47368 – enetc: Fix illegal access when reading affinity_hint

21 May 2024 — In the Linux kernel, the following vulnerability has been resolved: enetc: Fix illegal access when reading affinity_hint irq_set_affinity_hit() stores a reference to the cpumask_t parameter in the irq descriptor, and that reference can be accessed later from irq_affinity_hint_proc_show(). Since the cpu_mask parameter passed to irq_set_affinity_hit() has only temporary storage (it's on the stack memory), later accesses to it are illegal. Thus reads from the corresponding procfs affinity_hint file can result ... • https://git.kernel.org/stable/c/d4fd0404c1c95b17880f254ebfee3485693fa8ba • CWE-400: Uncontrolled Resource Consumption •
CVE-2021-47366 – afs: Fix corruption in reads at fpos 2G-4G from an OpenAFS server

This is a problem, however, since the file position and length fields of FS.FetchData are *signed* 32-bit values.

CVE-2021-47364 – comedi: Fix memory leak in compat_insnlist()
https://notcve.org/view.php?id=CVE-2021-47364
21 May 2024 — In the Linux kernel, the following vulnerability has been resolved: comedi: Fix memory leak in compat_insnlist() `compat_insnlist()` handles the 32-bit version of the `COMEDI_INSNLIST` ioctl (whenwhen `CONFIG_COMPAT` is enabled). It allocates memory to temporarily hold an array of `struct comedi_insn` converted from the 32-bit version in user space. This memory is only being freed if there is a fault while filling the array, otherwise it is leaked. Add a call to `kfree()` to fix the leak.

During the subsequent initialization, set_power_state gets called to transition to the final power state. set_power_state refers to values from the current state and without current state populated, it could result in NULL pointer dereference.

21 May 2024 — In the Linux kernel, the following vulnerability has been resolved: mcb: fix error handling in mcb_alloc_bus() There are two bugs: 1) If ida_simple_get() fails then this code calls put_device(carrier) but we haven't yet called get_device(carrier) and probably that leads to a use after free. 2) After device_initialize() then we need to use put_device() to release the bus. This will free the internal resources tied to the device and call mcb_free_bus() which will free the rest.

CVE-2021-47360 – binder: make sure fd closes complete

21 May 2024 — In the Linux kernel, the following vulnerability has been resolved: binder: make sure fd closes complete During BC_FREE_BUFFER processing, the BINDER_TYPE_FDA object cleanup may close 1 or more fds. The close operations are completed using the task work mechanism -- which means the thread needs to return to userspace or the file object may never be dereferenced -- which can lead to hung processes.
