In the Linux kernel, the following vulnerability has been resolved: wifi: mac80211: Fix UAF in ieee80211_scan_rx() ieee80211_scan_rx() tries to access scan_req->flags after a null check, but a UAF is observed when the scan is completed and __ieee80211_scan_completed() executes, which then calls cfg80211_scan_done() leading to the freeing of scan_req. Since scan_req is rcu_dereference()'d, prevent the racing in __ieee80211_scan_completed() by ensuring that from mac80211's POV it is no longer accessed from an RCU read critical section before we call cfg80211_scan_done().

  - In the Linux kernel, the following vulnerability has been resolved: pid: take a reference when     initializing `cad_pid` During boot, kernel_init_freeable() initializes `cad_pid` to the init task's struct     pid. Later on, we may change `cad_pid` via a sysctl, and when this happens proc_do_cad_pid() will     increment the refcount on the new pid via get_pid(), and will decrement the refcount on the old pid via     put_pid(). As we never called get_pid() when we initialized `cad_pid`, we decrement a reference we never     incremented, can therefore free the init task's struct pid early. As there can be dangling references to     the struct pid, we can later encounter a use-after-free (e.g. when delivering signals). This was spotted     when fuzzing v5.13-rc3 with Syzkaller, but seems to have been around since the conversion of `cad_pid` to     struct pid in commit 9ec52099e4b8 ([PATCH] replace cad_pid by a struct pid) from the pre-KASAN stone age     of v2.6.19. Fix this by getting a reference to the init task's struct pid when we assign it to `cad_pid`.

  - In the Linux kernel, the following vulnerability has been resolved: i2c: i801: Don't generate an interrupt     on bus reset Now that the i2c-i801 driver supports interrupts, setting the KILL bit in a attempt to     recover from a timed out transaction triggers an interrupt. Unfortunately, the interrupt handler     (i801_isr) is not prepared for this situation and will try to process the interrupt as if it was signaling     the end of a successful transaction. In the case of a block transaction, this can result in an out-of-     range memory access. This condition was reproduced several times by syzbot:
    https://syzkaller.appspot.com/bug?extid=ed71512d469895b5b34e     https://syzkaller.appspot.com/bug?extid=8c8dedc0ba9e03f6c79e     https://syzkaller.appspot.com/bug?extid=c8ff0b6d6c73d81b610e     https://syzkaller.appspot.com/bug?extid=33f6c360821c399d69eb     https://syzkaller.appspot.com/bug?extid=be15dc0b1933f04b043a     https://syzkaller.appspot.com/bug?extid=b4d3fd1dfd53e90afd79 So disable interrupts while trying to reset     the bus. Interrupts will be enabled again for the following transaction. (CVE-2021-47153)

  - In the Linux kernel, the following vulnerability has been resolved: scsi: target: Fix WRITE_SAME No Data     Buffer crash In newer version of the SBC specs, we have a NDOB bit that indicates there is no data buffer     that gets written out. If this bit is set using commands like sg_write_same --ndob we will crash in     target_core_iblock/file's execute_write_same handlers when we go to access the se_cmd->t_data_sg because     its NULL. This patch adds a check for the NDOB bit in the common WRITE SAME code because we don't support     it. And, it adds a check for zero SG elements in each handler in case the initiator tries to send a normal     WRITE SAME with no data buffer. (CVE-2022-21546)

  - In the Linux kernel, the following vulnerability has been resolved: net/mlx5e: IPoIB, Block PKEY     interfaces with less rx queues than parent A user is able to configure an arbitrary number of rx queues     when creating an interface via netlink. This doesn't work for child PKEY interfaces because the child     interface uses the parent receive channels. Although the child shares the parent's receive channels, the     number of rx queues is important for the channel_stats array: the parent's rx channel index is used to     access the child's channel_stats. So the array has to be at least as large as the parent's rx queue size     for the counting to work correctly and to prevent out of bound accesses. This patch checks for the     mentioned scenario and returns an error when trying to create the interface. The error is propagated to     the user. (CVE-2022-48883)

  - In the Linux kernel, the following vulnerability has been resolved: ath9k_htc: fix potential out of bounds     access with invalid rxstatus->rs_keyix The rxstatus->rs_keyix eventually gets passed to test_bit() so we     need to ensure that it is within the bitmap. drivers/net/wireless/ath/ath9k/common.c:46     ath9k_cmn_rx_accept() error: passing untrusted data 'rx_stats->rs_keyix' to 'test_bit()' (CVE-2022-49503)

The CentOS Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the TuxCare CENTOS7:CLSA-2026:1788170774 advisory.

  - A race condition in Linux kernel SCTP sockets (net/sctp/socket.c) before 5.12-rc8 can lead to kernel     privilege escalation from the context of a network service or an unprivileged process. If     sctp_destroy_sock is called without sock_net(sk)->sctp.addr_wq_lock then an element is removed from the     auto_asconf_splist list without any proper locking. This can be exploited by an attacker with network     service privileges to escalate to root or from the context of an unprivileged user directly if a     BPF_CGROUP_INET_SOCK_CREATE is attached which denies creation of some SCTP socket. (CVE-2021-23133)

  - In the Linux kernel, the following vulnerability has been resolved: drm: Fix use-after-free read in     drm_getunique() There is a time-of-check-to-time-of-use error in drm_getunique() due to retrieving     file_priv->master prior to locking the device's master mutex. An example can be seen in the crash report     of the use-after-free error found by Syzbot:
    https://syzkaller.appspot.com/bug?id=148d2f1dfac64af52ffd27b661981a540724f803 In the report, the master     pointer was used after being freed. This is because another process had acquired the device's master mutex     in drm_setmaster_ioctl(), then overwrote fpriv->master in drm_new_set_master(). The old value of     fpriv->master was subsequently freed before the mutex was unlocked. To fix this, we lock the device's     master mutex before retrieving the pointer from from fpriv->master. This patch passes the Syzbot     reproducer test. (CVE-2021-47280)

  - In the Linux kernel, the following vulnerability has been resolved: scsi: mpt3sas: Fix kernel panic during     drive powercycle test While looping over shost's sdev list it is possible that one of the drives is     getting removed and its sas_target object is freed but its sdev object remains intact. Consequently, a     kernel panic can occur while the driver is trying to access the sas_address field of sas_target object     without also checking the sas_target object for NULL. (CVE-2021-47565)

  - In the Linux kernel, the following vulnerability has been resolved: dm btree remove: fix use after free in     rebalance_children() Move dm_tm_unlock() after dm_tm_dec(). (CVE-2021-47600)

  - In the Linux kernel, the following vulnerability has been resolved: media: pvrusb2: fix array-index-out-     of-bounds in pvr2_i2c_core_init Syzbot reported that -1 is used as array index. The problem was in missing     validation check. hdw->unit_number is initialized with -1 and then if init table walk fails this value     remains unchanged. Since code blindly uses this member for array indexing adding sanity check is the     easiest fix for that. hdw->workpoll initialization moved upper to prevent warning in __flush_work.
