CVE-2022-49722 ice: Fix memory corruption in VF driver

In the Linux kernel, the following vulnerability has been resolved: ice: Fix memory corruption in VF driver Disable VF's RX/TX queues, when it's disabled. VF can have queues enabled, when it requests a reset. If PF driver assumes that VF is disabled, while VF still has queues configured, VF may...

CVE-2022-49722

CVE-2022-49722 concerns memory corruption in the Linux kernel’s ice VF (virtual function) driver. The issue occurs when a VF’s RX/TX queues are not correctly disabled after a reset, allowing DMA resources to remain unmapped while queues are active, which can lead the device to map packets to memo...

CVE-2022-49720

The CVE-2022-49720 entry is valid and supported by multiple connected advisories. The vulnerability resides in the Linux kernel block layer, specifically in blk_mq_alloc_request_hctx, where offline-queue handling could trigger a UBSAN array-index-out-of-bounds condition (index 512 out of 512 elem...

CVE-2022-49720 block: Fix handling of offline queues in blk_mq_alloc_request_hctx()

In the Linux kernel, the following vulnerability has been resolved: block: Fix handling of offline queues in blkmqallocrequesthctx This patch prevents that test nvme/004 triggers the following: UBSAN: array-index-out-of-bounds in block/blk-mq.h:135:9 index 512 is out of range for type 'long...

CVE-2022-49412 bfq: Avoid merging queues with different parents

In the Linux kernel, the following vulnerability has been resolved: bfq: Avoid merging queues with different parents It can happen that the parent of a bfqq changes between the moment we decide two queues are worth to merge and set bic-stablemergebfqq and the moment bfqsetupmerge is called. This...

CVE-2022-49378 sfc: fix considering that all channels have TX queues

In the Linux kernel, the following vulnerability has been resolved: sfc: fix considering that all channels have TX queues Normally, all channels have RX and TX queues, but this is not true if modparam efxseparatetxchannels=1 is used. In that cases, some channels only have RX queues and others onl...

CVE-2022-49378

CVE-2022-49378 concerns a Linux kernel driver issue in the sfc/efx10 path where TX queue initialization can fail when modparam efx_separate_tx_channels=1 causes some channels to have only RX or only TX queues. The root cause is an incorrect determination of whether a channel has TX queues, which ...

CVE-2022-49326

CVE-2022-49326 affects RTL818x wireless in Linux kernel (rtl8180/rtl8185/rtl8187se family). The issue arises from using not initialized tx queues, where reading ring->entries when zero can crash the kernel. The fix patches the driver to ignore priority for cards with a single TX queue and to p...

CVE-2022-49326 rtl818x: Prevent using not initialized queues

In the Linux kernel, the following vulnerability has been resolved: rtl818x: Prevent using not initialized queues Using not existing queues can panic the kernel with rtl8180/rtl8185 cards. Ignore the skb priority for those cards, they only have one tx queue. Pierre Asselin [email protected] reported t...

CVE-2022-49096

Summary (CVE-2022-49096): In the Linux kernel net/sfc driver, changing rx/tx ring buffer size with ethtool -G led to a kernel panic when handling XDP_TX or XDP_REDIRECT because xdp queues (efx->xdp_tx_queues) were not reinitialized. The root cause was missing reinitialization of the XDP queues...

CVE-2022-49096 net: sfc: add missing xdp queue reinitialization

In the Linux kernel, the following vulnerability has been resolved: net: sfc: add missing xdp queue reinitialization After rx/tx ring buffer size is changed, kernel panic occurs when it acts XDPTX or XDPREDIRECT. When tx/rx ring buffer size is changedethtool -G, sfc driver reallocates and...
