    drm: Don't unref the same fb many times by mistake due to deadlock handling(CVE-2023-52486)

    A flaw was found in the Netfilter subsystem in the Linux kernel. The issue is in the nft_byteorder_eval()     function, where the code iterates through a loop and writes to the `dst` array. On each iteration, 8 bytes     are written, but `dst` is an array of u32, so each element only has space for 4 bytes. That means every     iteration overwrites part of the previous element corrupting this array of u32. This flaw allows a local     user to cause a denial of service or potentially break NetFilter functionality.(CVE-2024-0607)

    blk-mq: fix IO hang from sbitmap wakeup race(CVE-2024-26671)

    bus: qcom: Put child node before return(CVE-2021-47054)

    A vulnerability was reported in the Open vSwitch sub-component in the Linux Kernel. The flaw occurs when a     recursive operation of code push recursively calls into the code block. The OVS module does not validate     the stack depth, pushing too many frames and causing a stack overflow. As a result, this can lead to a     crash or other related issues.(CVE-2024-1151)

    A use-after-free flaw was found in the Linux kernel's NFC LLCP protocol implementation in the way the user     performs manipulation with an unknown input for the llcp_sock_bind() function. This flaw allows a local     user to crash or escalate their privileges on the system. (CVE-2020-25670)

    A use-after-free flaw was found in the Linux kernel's NFC LLCP protocol implementation in the way the user     triggers the llcp_sock_connect() function. This flaw allows a local user to crash the system.
    (CVE-2020-25671)

    A memory leak in the Linux kernel's NFC LLCP protocol implementation was found in the way a user triggers     the llcp_sock_connect() function. This flaw allows a local user to starve the resources, causing a denial     of service. (CVE-2020-25672)

    A vulnerability was found in Linux kernel where non-blocking socket in llcp_sock_connect() leads to leak     and eventually hanging-up the system. (CVE-2020-25673)

    A use-after-free flaw was found in the Linux kernel's SCTP socket functionality that triggers a race     condition. This flaw allows a local user to escalate their privileges on the system. The highest threat     from this vulnerability is to confidentiality, integrity, as well as system availability. (CVE-2021-23133)

    A vulnerability was discovered in retrieve_ptr_limit in kernel/bpf/verifier.c in the Linux kernel     mechanism to mitigate speculatively out-of-bounds loads (Spectre mitigation). In this flaw a local,     special user privileged (CAP_SYS_ADMIN) BPF program running on affected systems may bypass the protection,     and execute speculatively out-of-bounds loads from the kernel memory. This can be abused to extract     contents of kernel memory via side-channel. (CVE-2021-29155)

    A flaw was found in the Linux kernel's eBPF verification code. By default, accessing the eBPF verifier is     only accessible to privileged users with CAP_SYS_ADMIN. This flaw allows a local user who can insert eBPF     instructions, to use the eBPF verifier to abuse a spectre-like flaw and infer all system memory. The     highest threat from this vulnerability is to confidentiality. (CVE-2021-31829)

    The eBPF RINGBUF bpf_ringbuf_reserve() function in the Linux kernel did not check that the allocated size     was smaller than the ringbuf size, allowing an attacker to perform out-of-bounds writes within the kernel     and therefore, arbitrary code execution. This issue was fixed via commit 4b81ccebaeee (bpf, ringbuf: Deny     reserve of buffers larger than ringbuf) (v5.13-rc4) and backported to the stable kernels in v5.12.4,     v5.11.21, and v5.10.37. It was introduced via 457f44363a88 (bpf: Implement BPF ring buffer and verifier     support for it) (v5.8-rc1). (CVE-2021-3489)

    The eBPF ALU32 bounds tracking for bitwise ops (AND, OR and XOR) in the Linux kernel did not properly     update 32-bit bounds, which could be turned into out of bounds reads and writes in the Linux kernel and     therefore, arbitrary code execution. This issue was fixed via commit 049c4e13714e (bpf: Fix alu32 const     subreg bound tracking on bitwise operations) (v5.13-rc4) and backported to the stable kernels in v5.12.4,     v5.11.21, and v5.10.37. The AND/OR issues were introduced by commit 3f50f132d840 (bpf: Verifier, do     explicit ALU32 bounds tracking) (5.7-rc1) and the XOR variant was introduced by 2921c90d4718 (bpf:Fix a     verifier failure with xor) ( 5.10-rc1). (CVE-2021-3490)

    A flaw was found in the Linux kernel.  The io_uring PROVIDE_BUFFERS operation allowed the MAX_RW_COUNT     limit to be bypassed, which led to negative values being used in mem_rw when reading /proc/<PID>/mem. The     highest threat from this vulnerability is to data confidentiality and integrity as well as system     availability. (CVE-2021-3491)

    A flaw was found in the Linux kernel in versions before 5.12. The value of internal.ndata, in the KVM API,     is mapped to an array index, which can be updated by a user process at anytime which could lead to an out-     of-bounds write. The highest threat from this vulnerability is to data integrity and system availability.
    (CVE-2021-3501)

    In the Linux kernel, the following vulnerability has been resolved:

    net: hso: fix null-ptr-deref during tty device unregistration

    Multiple ttys try to claim the same the minor number causing a doubleunregistration of the same device.
    The first unregistration succeedsbut the next one results in a null-ptr-deref.

    The get_free_serial_index() function returns an available minor numberbut doesn't assign it immediately.
    The assignment is done by the callerlater. But before this assignment, calls to     get_free_serial_index()would return the same minor number.

    Fix this by modifying get_free_serial_index to assign the minor numberimmediately after one is found to be     and rename it to obtain_minor()to better reflect what it does. Similary, rename set_serial_by_index()to     release_minor() and modify it to free up the minor number of thegiven hso_serial. Every obtain_minor()     should have correspondingrelease_minor() call. (CVE-2021-46904)

    In the Linux kernel, the following vulnerability has been resolved:

    net: hso: fix NULL-deref on disconnect regression

    Commit 8a12f8836145 (net: hso: fix null-ptr-deref during tty deviceunregistration) fixed the racy minor     allocation reported by syzbot, butintroduced an unconditional NULL-pointer dereference on every     disconnectinstead.

    Specifically, the serial device table must no longer be accessed afterthe minor has been released by     hso_serial_tty_unregister(). (CVE-2021-46905)

    In the Linux kernel, the following vulnerability has been resolved:

    bpf: Use correct permission flag for mixed signed bounds arithmetic

    We forbid adding unknown scalars with mixed signed bounds due to thespectre v1 masking mitigation. Hence     this also needs bypass_spec_v1flag instead of allow_ptr_leaks. (CVE-2021-46908)

    In the Linux kernel, the following vulnerability has been resolved:

    ARM: footbridge: fix PCI interrupt mapping (CVE-2021-46909)

    In the Linux kernel, the following vulnerability has been resolved:

    net: Make tcp_allowed_congestion_control readonly in non-init netns (CVE-2021-46912)

    A use-after-free flaw was found in the Linux kernel's NFC LLCP protocol implementation in the way the user     performs manipulation with an unknown input for the llcp_sock_bind() function. This flaw allows a local     user to crash or escalate their privileges on the system. (CVE-2020-25670)

    A use-after-free flaw was found in the Linux kernel's NFC LLCP protocol implementation in the way the user     triggers the llcp_sock_connect() function. This flaw allows a local user to crash the system.
    (CVE-2020-25671)

    A memory leak in the Linux kernel's NFC LLCP protocol implementation was found in the way a user triggers     the llcp_sock_connect() function. This flaw allows a local user to starve the resources, causing a denial     of service. (CVE-2020-25672)

    A vulnerability was found in Linux kernel where non-blocking socket in llcp_sock_connect() leads to leak     and eventually hanging-up the system. (CVE-2020-25673)

    A use-after-free flaw was found in the Linux kernel's SCTP socket functionality that triggers a race     condition. This flaw allows a local user to escalate their privileges on the system. The highest threat     from this vulnerability is to confidentiality, integrity, as well as system availability. (CVE-2021-23133)

    A flaw was found in the Linux kernels eBPF implementation. By default, accessing the eBPF verifier is only     accessible to privileged users with CAP_SYS_ADMIN.   A local user with the ability to insert eBPF     instructions can abuse a flaw in eBPF to corrupt memory. The highest threat from this vulnerability is to     confidentiality, integrity, as well as system availability. (CVE-2021-29154)

    A vulnerability was discovered in retrieve_ptr_limit in kernel/bpf/verifier.c in the Linux kernel     mechanism to mitigate speculatively out-of-bounds loads (Spectre mitigation). In this flaw a local,     special user privileged (CAP_SYS_ADMIN) BPF program running on affected systems may bypass the protection,     and execute speculatively out-of-bounds loads from the kernel memory. This can be abused to extract     contents of kernel memory via side-channel. (CVE-2021-29155)

    A flaw was found in the Linux kernel's eBPF verification code. By default, accessing the eBPF verifier is     only accessible to privileged users with CAP_SYS_ADMIN. This flaw allows a local user who can insert eBPF     instructions, to use the eBPF verifier to abuse a spectre-like flaw and infer all system memory. The     highest threat from this vulnerability is to confidentiality. (CVE-2021-31829)

    In the Linux kernel, the following vulnerability has been resolved:

    net: hso: fix null-ptr-deref during tty device unregistration

    Multiple ttys try to claim the same the minor number causing a doubleunregistration of the same device.
    The first unregistration succeedsbut the next one results in a null-ptr-deref.

    The get_free_serial_index() function returns an available minor numberbut doesn't assign it immediately.
    The assignment is done by the callerlater. But before this assignment, calls to     get_free_serial_index()would return the same minor number.

    Fix this by modifying get_free_serial_index to assign the minor numberimmediately after one is found to be     and rename it to obtain_minor()to better reflect what it does. Similary, rename set_serial_by_index()to     release_minor() and modify it to free up the minor number of thegiven hso_serial. Every obtain_minor()     should have correspondingrelease_minor() call. (CVE-2021-46904)

    In the Linux kernel, the following vulnerability has been resolved:

    net: hso: fix NULL-deref on disconnect regression

    Commit 8a12f8836145 (net: hso: fix null-ptr-deref during tty deviceunregistration) fixed the racy minor     allocation reported by syzbot, butintroduced an unconditional NULL-pointer dereference on every     disconnectinstead.

    Specifically, the serial device table must no longer be accessed afterthe minor has been released by     hso_serial_tty_unregister(). (CVE-2021-46905)

    In the Linux kernel, the following vulnerability has been resolved:

    ARM: footbridge: fix PCI interrupt mapping (CVE-2021-46909)

    In the Linux kernel, the following vulnerability has been resolved:
