In the Linux kernel, the following vulnerabilities have been resolved: cxl: Fixed a memory leak in the error handling path. The bitmapzalloc function must be balanced with a corresponding bitmapfree function in the error handling path of afuallocateirqs...

Astra Linux – Vulnerability in Linux 5.10, Linux

In the Linux kernel, the following vulnerability has been resolved: Staging: rtl8723bs – fixed a potential memory leak in rtwinitcmdpriv. In rtwinitcmdpriv, if pcmdpriv-rspallocatedbuf is allocated incorrectly, then pcmdpriv-cmdallocatedbuf will not be released properly. Additionally, since there...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: usb: dwc3: st: fixed the issue where the reference count of the platform device was checked during the error path. The probe function never performs any platform device allocation. Therefore, the error path “undoplatformdevalloc”...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: xprtrdma: fixed pointer dereferencing in error cases of rpcrdmaepcreate. If there are failures, we must not leave non-NULL pointers with error values. Otherwise, rpcrdmaepDestroy will be confused and try to free those pointers...

Astra Linux – Vulnerability in Linux, Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: dma-buf/syncfile: Do not leak fences during merge failures. Each call to addfence performs a dmafenceget operation on the relevant fence. In error-prone scenarios, we did not call dmafenceput, resulting in all those fences bei...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: remoteproc: core: Fix idafree call while not allocated In the rprocalloc function, when an error occurs, the putdevice&rproc-dev call is made, leading to the invocation of the rproctyperelease function. An error can occur before...
