So precisely the same treatment method should be placed on all DSA swap drivers, which can be: both use devres for equally the mdiobus allocation and registration, or Will not use devres in any respect. The felix driver has the code framework in place for orderly mdiobus removing, so just replace devm_mdiobus_alloc_size() with the non-devres variant, and include manual free of charge where by important, in order that we do not Allow devres no cost a even now-registered bus.
while in the Linux kernel, the next vulnerability is fixed: NFSD: correct ia_size underflow iattr::ia_size is usually a loff_t, that is a signed sixty four-little bit sort. NFSv3 and NFSv4 each define file dimensions as an unsigned 64-bit variety. Therefore There is certainly An array of valid file dimension values an NFS client can send which is currently much larger than Linux can take care of.
before commit 45bf39f8df7f ("USB: core: Do not hold product lock whilst studying the "descriptors" sysfs file") this race could not come about, since the routines had been mutually distinctive due to the machine locking. getting rid of that locking from read_descriptors() exposed it for the race. The easiest method to take care of the bug is to help keep hub_port_init() from changing udev->descriptor the moment udev is initialized and registered. Drivers expect the descriptors stored while in the kernel to get immutable; we should not undermine this expectation. actually, this modification ought to have been designed long ago. So now hub_port_init() will just take an additional argument, specifying a buffer wherein to store the system descriptor it reads. (If udev has not yet been initialized, the buffer pointer will probably be NULL and after that hub_port_init() will store the machine descriptor in udev as ahead of.) This gets rid of the information race responsible for the out-of-bounds go through. The changes to hub_port_init() appear extra substantial than they really are, as a result of indentation variations resulting from an attempt to stay away from composing to other elements of the usb_device composition just after it has been initialized. comparable adjustments should be produced for the code that reads the BOS descriptor, but which can be managed within a individual patch afterward. This patch is sufficient to repair the bug found by syzbot.
So it is crucial to carry that mutex. in any other case a sysfs browse can trigger an oops. Commit 17f09d3f619a ("SUNRPC: Test When the xprt is connected just before managing sysfs reads") seems to try to resolve this issue, but it only narrows the race window.
In the Linux kernel, the following vulnerability continues to be fixed: drm/amdgpu: bypass tiling flag check in virtual display scenario (v2) vkms leverages typical amdgpu framebuffer generation, in addition to as it does not assistance FB bprom promoter modifier, there isn't a need to have to check tiling flags when initing framebuffer when virtual display is enabled.
A vulnerability inside the package_index module of pypa/setuptools variations as many as 69.one.one allows for remote code execution by using its down load features. These features, that are used to download offers from URLs provided by people or retrieved from package deal index servers, are vulnerable to code injection.
php. The manipulation of your argument type leads to cross web-site scripting. It is achievable to launch the attack remotely. The exploit has been disclosed to the public and should be utilised. The identifier of this vulnerability is VDB-271932.
Rework the parser logic by first checking the real partition variety and afterwards allocate the space and established the information for your legitimate partitions. The logic was also fundamentally wrong as with a skipped partition, the pieces variety returned was incorrect by not lowering it for that skipped partitions.

during the Linux kernel, the next vulnerability continues to be resolved: Web/mlx5: correct a race on command flush circulation take care of a refcount use soon after no cost warning on account of a race on command entry. these types of race occurs when one of many instructions releases its last refcount and frees its index and entry whilst A different process operating command flush stream normally takes refcount to this command entry. The process which handles commands flush may see this command as needed to be flushed if another process launched its refcount but didn't launch the index but.
The vulnerability allows an attacker to bypass the authentication specifications for a particular PAM endpoint.
So precisely the same cure has to be applied to all DSA switch drivers, that is: either use devres for equally the mdiobus allocation and registration, or don't use devres in any way. The bcm_sf2 driver has the code construction in spot for orderly mdiobus elimination, so just swap devm_mdiobus_alloc() with the non-devres variant, and add handbook cost-free exactly where required, making sure that we don't Permit devres free a still-registered bus.
So the identical cure need to be applied to all DSA switch motorists, that is: possibly use devres for both equally the mdiobus allocation and registration, or You should not use devres at all. The gswip driver has the code structure in spot for orderly mdiobus elimination, so just replace devm_mdiobus_alloc() with the non-devres variant, and include handbook cost-free in which vital, in order that we do not Allow devres totally free a however-registered bus.
