In the Linux kernel, the following vulnerability has been resolved: tty: serial: fsllpuart: disable dma rx/tx use flags in lpuartdmashutdown lpuartdmashutdown tears down the lpuart DMA mechanism, but lpuartFlushBuffer can still occur. This attempt to access DMA APIs occurs if the lpuartDMATXuse...

Astra Linux – Vulnerability found in Linux 6.1, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: ACPI: CPPC: Use accesswidth instead of bitwidth for system memory accesses To comply with ACPI 6.3+, since bitwidth can be any 8-bit value, it cannot be relied upon to always be at a clean 8-bit boundary. This issue was discovere...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: RDMA/efa: Fixed the incorrect order of resource deallocation. When attempting to destroy a QP or CQ, we first reduce the reference count and potentially free the memory regions allocated for the object. Then, we request the devic...

Astra Linux – Vulnerability found in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: RDMA/bnxtre: wraparound mbox producer index The driver does not handle the wraparound of the mbox producer index correctly. Currently, the wraparound occurs once the u32 maximum value is reached. Bit 31 of the producer index...

Astra Linux – Vulnerability in libmysofa

Incorrect handling of input data in the loudness function of the libmysofa library in versions 0.5 to 1.1 can lead to heap buffer overflows and access to unallocated memory blocks...

Astra Linux – Vulnerability in Linux

An out-of-bounds memory access flaw was discovered in the x25bind function in the net/x25/afx25.c file within the Linux kernel version v5.12-rc5. A failure in the bounds check allows a local attacker with a user account on the system to access out-of-bounds memory, resulting in a system crash or...

Astra Linux – Vulnerability in PHP 7.3

In PHP versions 7.2.x below 7.2.33, 7.3.x below 7.3.21, and 7.4.x below 7.4.9, when processing PHAR files using the phar extension, pharparsezipfile might be tricked into accessing freed memory, which could lead to a crash or information disclosure...

Astra Linux – Vulnerability in Linux

An out-of-bounds memory access flaw was discovered in the fs/f2fs/node.c file within the f2fs module of the Linux kernel, in versions prior to 5.12.0-rc4. A failure in the bounds check allows a local attacker to gain access to out-of-bounds memory, resulting in a system crash or the leakage of...

Astra Linux – Vulnerability in Linux

In the Linux kernel, the following vulnerability has been resolved: spi: spi-fsl-dspi: A resource leak was fixed in the error handling path. The call dspirequestdma should be undone by a call to dspireleasedma in the error handling path of the probe function, as already done in the remove functio...

Astra Linux – Vulnerability in Qemu

A buffer overflow vulnerability was discovered in the ATI VGA device emulation provided by QEMU. This vulnerability occurs in the ati2dblt routine, during the handling of MMIO write operations, when the guest provides invalid values for the destination display parameters. A malicious guest could...

Astra Linux – Vulnerability in Linux

A flaw was discovered in the KVM’s AMD code, which handles SVM nested virtualization. The flaw occurs during the processing of the VMCB virtual machine control block provided by the L1 guest to spawn/handle a nested guest L2. Due to improper validation of the “virtext” field, this issue could all...

Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerabilities have been resolved: RDMA/irdma: Fixed the bug where sleep operations occurred from an invalid context. RoCEv2 QP processing in netdev events caused a kernel split. This issue was fixed by removing the handling of RoCEv2 in...

Astra Linux – Vulnerability in Linux 5.10, Linux

A flaw in the boot CPU could be exploited by attacks targeting speculative execution behavior. This flaw is related to the power management options in the Linux kernel’s X86 CPU. It was discovered in the way users resume the CPU from suspend-to-RAM. A local user could utilize this flaw to...

Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15

A flaw was discovered in the udmabuf device driver of the Linux kernel, within a fault handler. This issue arises due to the lack of proper validation of user-supplied data, which can lead to memory access beyond the end of an array. This may allow an attacker to escalate privileges and execute...

Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: riscv/kprobe: Fixed instruction simulation for JALR. Setting kprobe at ‘jalr 1140ra’ in vfswrite results in the following crash’: 32.092235 Unable to handle kernel access to user memory without uaccess routines at virtual address...

Astra Linux – Vulnerability in Qemu

A heap buffer overflow was discovered in the floppy disk emulator of QEMU up to version 6.0.0 inclusive. This issue could occur in the fdctrltransferhandler function in the hw/block/fdc.c file, during the processing of DMA read data transfers from the floppy drive to the guest system. A privilege...

Astra Linux – Vulnerability in Qemu

A flaw was discovered in the QEMU implementation of VMWare’s paravirtual RDMA device. This flaw allows a malicious guest driver to allocate and initialize a large number of page tables, which can be used as a ring of descriptors for CQ and async events. This could potentially lead to out-of-bound...

Astra Linux – Vulnerability in xorg-server

A vulnerability was discovered in X.Org. This security flaw arises because the XkbCopyNames function left a dangling pointer pointing to freed memory, allowing for out-of-bounds memory access during subsequent XkbGetKbdByName requests. This issue can lead to local privileges escalation on systems...
