  - 已修复 Linux 内核中的下列漏洞：rpmsg: char: Fix race between the release of rpmsg_ctrldev and cdev struct rpmsg_ctrldev contains a struct cdev. The current code frees the rpmsg_ctrldev struct in rpmsg_ctrldev_release_device(), but the cdev is a managed object, therefore its release is not predictable and the rpmsg_ctrldev could be freed before the cdev is entirely released, as in the backtrace below.

  - 已修复 Linux 内核中的下列漏洞：dm integrity: fix memory corruption when tag_size is less than digest size It is possible to set up dm-integrity in such a way that the tag_size parameter is less than the actual digest size. In this situation, a part of the digest beyond tag_size is ignored. In this case, dm-integrity would write beyond the end of the ic->recalc_tags array and corrupt memory. The corruption happened in integrity_recalc->integrity_sector_checksum->crypto_shash_final. Fix this corruption by increasing the tags array so that it has enough padding at the end to accomodate the loop in integrity_recalc() being able to write a full digest size for the last member of the tags array. (CVE-2022-49044)

  - 已修复 Linux 内核中的下列漏洞：ata: sata_dwc_460ex: Fix crash due to OOB write the driver uses libata's tag values from in various arrays. Since the mentioned patch bumped the ATA_TAG_INTERNAL to 32, the value of the SATA_DWC_QCMD_MAX needs to account for that. Otherwise ATA_TAG_INTERNAL usage cause similar crashes like this as reported by Tice Rex on the OpenWrt Forum and reproduced (with symbols) here: | BUG: Kernel NULL pointer dereference at 0x00000000 | Faulting instruction address: 0xc03ed4b8 | Oops: Kernel access of bad area, sig: 11 [#1] | BE PAGE_SIZE=4K PowerPC 44x Platform | CPU: 0 PID: 362 Comm: scsi_eh_1 Not tainted 5.4.163 #0 | NIP: c03ed4b8 LR: c03d27e8 CTR:

    dma_dwc_xfer_setup() passes the NULL'd hsdevp->chan to the dmaengine_slave_config() which then causes the crash. With this patch, SATA_DWC_QCMD_MAX is now set to ATA_MAX_QUEUE + 1. This avoids the OOB. But please note, there was a worthwhile discussion on what ATA_TAG_INTERNAL and ATA_MAX_QUEUE is. And why there should not be a fake 33 command-long queue size. Ideally, the dw driver should account for the ATA_TAG_INTERNAL. In Damien Le Moal's words: ... having looked at the driver, it is a bigger change than just faking a 33rd tag that is in fact not a command tag at all. BugLink:

如 TuxCare CENTOS8.4：CLSA-2025：1763731262公告所述，CentOS Linux 8.4 主机上安装的程序包受到多个漏洞的影响。

  - 在 Samsung Galaxy S3 i9305 4.4.4 设备中发现一个问题。只要前 8 个字节与 EAPOL 的有效 RFC1042（即 LLC/SNAP）标头一致，WEP、WPA、WPA2 和 WPA3 实现就可以接受明文 A-MSDU 帧。攻击者可能会滥用此漏洞，以注入与网络配置无关的任意网络数据包。(CVE-2020-26144)

  - 在 5.11.8 值之前的 Linux 内核中发现一个问题。kernel/bpf/verifier.c 在指针算法上执行不良的越界推测，进而导致边信道攻击，这可破坏 Spectre 缓解措施，并从内核内存获取敏感信息，即 CID-f232326f6966。这会影响未定义 ptr_limit 的指针类型。(CVE-2020-27170)

  - 在 5.11.8 值之前的 Linux 内核中发现一个问题。kernel/bpf/verifier.c 中存在差一错误（导致整数下溢），会影响指针算法上的越界推测，进而导致边信道攻击，这可破坏 Spectre 缓解措施，并从内核内存获取敏感信息，即 CID-10d2bb2e6b1d。(CVE-2020-27171)
