CVE-2021-47558

In the Linux kernel, the following vulnerability has been resolved: net: stmmac: Disable Tx queues when reconfiguring the interface The Tx queues were not disabled in situations where the driver needed to stop the interface to apply a new configuration. This could result in a kernel panic when...

CVE-2021-47561

In the Linux kernel, the following vulnerability has been resolved: i2c: virtio: disable timeout handling If a timeout is hit, it can result is incorrect data on the I2C bus and/or memory corruptions in the guest since the device can still be operating on the buffers it was given while the guest...

CVE-2021-47509

CVE-2021-47509 affects the Linux kernel ALSA: pcm: oss, where the period size could be exhaustively allocated due to an overly large 31-bit limit. The fix sets a practical period-size limit of 16 MB to prevent memory exhaustion from temporary OSS buffers. This remediation is reflected in multiple...

In the Linux kernel, the following vulnerability has been resolved: comedi: dt9812: fix DMA buffers on stack USB transfer buffers are typically mapped for DMA and must not be allocated on the stack or transfers will fail. Allocate proper transfer buffers in the various command helpers and return ...

CVE-2021-47475

A flaw was found in the vmk80xx module in the Linux kernel. Memory buffer allocations with incorrect sizes can result in an out-of-bounds write when performing descriptor fuzzing...

SUSE CVE-2021-47231

In the Linux kernel, the following vulnerability has been resolved: can: mcbausb: fix memory leak in mcbausb Syzbot reported memory leak in SocketCAN driver for Microchip CAN BUS Analyzer Tool. The problem was in unfreed usbcoherent. In mcbausbstart 20 coherent buffers are allocated and there is...

SUSE CVE-2021-47485

In the Linux kernel, the following vulnerability has been resolved: IB/qib: Protect from buffer overflow in struct qibusersdmapkt fields Overflowing either addrlimit or bytestogo can allow userspace to trigger a buffer overflow of kernel memory. Check for overflows in all the places doing math on...

SUSE CVE-2023-52767

In the Linux kernel, the following vulnerability has been resolved: tls: fix NULL deref on tlsswspliceeof with empty record syzkaller discovered that if tlsswspliceeof is executed as part of sendfile when the plaintext/ciphertext skmsg are empty, the send path gets confused because the empty...

python-cryptography: memory corruption via immutable objects

A vulnerability was found in python-cryptography. In affected versions, Cipher.updateinto would accept Python objects which implement the buffer protocol but provide only immutable buffers. This issue allows immutable objects such as bytes to be mutated, thus violating the fundamental rules of...
