Astra Linux – Vulnerability in Linux, Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: comedi: niusb6501: fixed NULL dereferencing in command paths. The driver uses USB transfer buffers of the endpoint size, but there were no sanity checks on their sizes. This can lead to dereferencing of zero-size pointers or...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: comedi: A memory leak has been fixed in compatinsnlist. compatinsnlist handles the 32-bit version of the COMEDIINSNLIST ioctl function when CONFIGCOMPAT is enabled. It allocates memory to temporarily hold an array of struct...

In the Linux kernel, the following vulnerability has been resolved: comedi: pcl812: Fix bit shift out of bounds When checking for a supported IRQ number, the following test is used: c if 1 options1 & board-irqbits However, it-optionsi is an unchecked int value from userspace, so the shift amount...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, Linux, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: comedi: Flushing partial mappings in the error case If some remappfnrange calls succeeded before one failed, we still have buffer pages mapped into the user-space page tables when we drop the buffer reference with...

Astra Linux – Vulnerability in Linux, Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: comedi: vmk80xx: fixed transfer-buffer overflows The driver uses USB transfer buffers sized at the endpoint level, but until recently, there were no sanity checks on these buffer sizes. The commit e1f13c879a7c “staging: comedi...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: “comedi: runflags cannot determine whether to reclaim chanlist” The syzbot reported a memory leak 1. This was because commit 4e1da516debb “comedi: Add reference counting for Comedi command handling” did not account for the...

Astra Linux – Vulnerability in Linux, Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: comedi: vmk80xx: fixed the bulk-buffer overflow issue. The driver uses buffers sized equal to the endpoint size, but it should not assume that the tx and rx buffers have the same size. A malicious device could cause the...

Astra Linux – Vulnerability in Linux, Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: comedi: dt9812 – fixed DMA buffers on the stack. USB transfer buffers are typically mapped for DMA operations, and they must not be allocated on the stack; otherwise, transfers will fail. Proper transfer buffers should be allocat...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, and Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: Comedi: Fixed the initialization of data for instructions that write to sub-devices. It is known that some Comedi sub-device instruction handlers access data elements beyond the first insn-n elements in some cases. The doinsnioct...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, and Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: The issue related to comedi: a race between polling and detaching the device has been fixed. The syzbot report indicates a use-after-free in the comedi module. This occurs because comedi happily removes the allocated async area,...
