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

    uio: Fix use-after-free in uio_open

    core-1                          core-2-------------------------------------------------------     uio_unregister_device              uio_openidev = idr_find()device_unregister(&idev->dev)put_device(&idev-     >dev)uio_device_releaseget_device(&idev->dev)kfree(idev)uio_free_minor(minor)uio_releaseput_device(&idev-     >dev)kfree(idev)-------------------------------------------------------

    In the core-1 uio_unregister_device(), the device_unregister will kfreeidev when the idev->dev kobject ref     is 1. But after core-1device_unregister, put_device and before doing kfree, the core-2 mayget_device.
    Then:1. After core-1 kfree idev, the core-2 will do use-after-free for idev.2. When core-2 do uio_release     and put_device, the idev will be doublefreed.

    To address this issue, we can get idev atomic & inc idev reference withminor_lock. (CVE-2023-52439)

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

    gfs2: Fix kernel NULL pointer dereference in gfs2_rgrp_dump

    Syzkaller has reported a NULL pointer dereference when accessingrgd->rd_rgl in gfs2_rgrp_dump().  This can     happen when creatingrgd->rd_gl fails in read_rindex_entry().  Add a NULL pointer check ingfs2_rgrp_dump()     to prevent that. (CVE-2023-52448)

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

    EDAC/thunderx: Fix possible out-of-bounds string access

    Enabling -Wstringop-overflow globally exposes a warning for a common bugin the usage of strncat():

    drivers/edac/thunderx_edac.c: In function     'thunderx_ocx_com_threaded_isr':drivers/edac/thunderx_edac.c:1136:17: error: 'strncat' specified bound     1024 equals destination size [-Werror=stringop-overflow=]1136 |                 strncat(msg, other,     OCX_MESSAGE_SIZE);|                 ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~...1145 |     strncat(msg, other, OCX_MESSAGE_SIZE);...1150 |                                 strncat(msg, other,     OCX_MESSAGE_SIZE);

    ...

    Apparently the author of this driver expected strncat() to behave theway that strlcat() does, which uses     the size of the destination bufferas its third argument rather than the length of the source buffer.
    Theresult is that there is no check on the size of the allocated buffer.

    Change it to strlcat().

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

    drivers/amd/pm: fix a use-after-free in kv_parse_power_table

    When ps allocated by kzalloc equals to NULL, kv_parse_power_tablefrees adev->pm.dpm.ps that allocated     before. However, after the controlflow goes through the following call chains:

    kv_parse_power_table|-> kv_dpm_init|-> kv_dpm_sw_init|-> kv_dpm_fini

    The adev->pm.dpm.ps is used in the for loop of kv_dpm_fini after itsfirst free in kv_parse_power_table and     causes a use-after-free bug. (CVE-2023-52469)

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

    drm/radeon: check the alloc_workqueue return value in radeon_crtc_init()

    check the alloc_workqueue return value in radeon_crtc_init()to avoid null-ptr-deref. (CVE-2023-52470)

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

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

    drm/amd/pm: fix a double-free in si_dpm_init (CVE-2023-52691)

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

    calipso: fix memory leak in netlbl_calipso_add_pass() (CVE-2023-52698)

    An out-of-bounds access vulnerability involving netfilter was reported and fixed as: f1082dd31fe4     (netfilter: nf_tables: Reject tables of unsupported family); While creating a new netfilter table, lack of     a safeguard against invalid nf_tables family (pf) values within `nf_tables_newtable` function enables an     attacker to achieve out-of-bounds access. (CVE-2023-6040)

    A race condition was found in the GSM 0710 tty multiplexor in the Linux kernel. This issue occurs when two     threads execute the GSMIOC_SETCONF ioctl on the same tty file descriptor with the gsm line discipline     enabled, and can lead to a use-after-free problem on a struct gsm_dlci while restarting the gsm mux. This     could allow a local unprivileged user to escalate their privileges on the system. (CVE-2023-6546)

    A Null pointer dereference problem was found in ida_free in lib/idr.c in the Linux Kernel. This issue may     allow an attacker using this library to cause a denial of service problem due to a missing check at a     function return. (CVE-2023-6915)

    An out-of-bounds memory read flaw was found in receive_encrypted_standard in fs/smb/client/smb2ops.c in     the SMB Client sub-component in the Linux Kernel. This issue occurs due to integer underflow on the memcpy     length, leading to a denial of service. (CVE-2024-0565)

    netfilter: nf_tables: fix pointer math issue in nft_byteorder_eval() (CVE-2024-0607)

    An out-of-bounds memory write flaw was found in the Linux kernel's Transport Layer Security functionality     in how a user calls a function splice with a ktls socket as the destination. This flaw allows a local user     to crash or potentially escalate their privileges on the system. (CVE-2024-0646)

    In rds_recv_track_latency in net/rds/af_rds.c in the Linux kernel through 6.7.1, there is an off-by-one     error for an RDS_MSG_RX_DGRAM_TRACE_MAX comparison, resulting in out-of-bounds access. (CVE-2024-23849)

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

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

    block: add check that partition length needs to be aligned with block size

    Before calling add partition or resize partition, there is no checkon whether the length is aligned with     the logical block size.If the logical block size of the disk is larger than 512 bytes,then the partition     size maybe not the multiple of the logical block size,and when the last sector is read, bio_truncate()     will adjust the bio size,resulting in an IO error if the size of the read command is smaller thanthe     logical block size.If integrity data is supported, this will alsoresult in a null pointer dereference when     calling bio_integrity_free. (CVE-2023-52458)

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

    bpf: fix check for attempt to corrupt spilled pointer (CVE-2023-52462)

    In the Linux kernel, the following vulnerability has been resolved: efivarfs: force RO when remounting if     SetVariable is not supported If SetVariable at runtime is not supported by the firmware we never assign a     callback for that function. At the same time mount the efivarfs as RO so no one can call that. However, we     never check the permission flags when someone remounts the filesystem as RW. As a result this leads to a     crash (CVE-2023-52463)

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

    mfd: syscon: Fix null pointer dereference in of_syscon_register()

    kasprintf() returns a pointer to dynamically allocated memorywhich can be NULL upon failure.
    (CVE-2023-52467)

This flaw allows a local user     to crash or potentially escalate their privileges on the system. (CVE-2024-0646)

    A use-after-free vulnerability in the Linux kernel's netfilter: nf_tables component can be exploited to     achieve local privilege escalation.

    The nft_setelem_catchall_deactivate() function checks whether the catch-all set element is active in the     current generation instead of the next generation before freeing it, but only flags it inactive in the     next generation, making it possible to free the element multiple times, leading to a double free     vulnerability.

    We recommend upgrading past commit b1db244ffd041a49ecc9618e8feb6b5c1afcdaa7. (CVE-2024-1085)

    In the Linux kernel, the following vulnerability has been resolved: mlxsw: spectrum_acl_tcam: Fix stack     corruption When tc filters are first added to a net device, the corresponding local port gets bound to an     ACL group in the device. (CVE-2024-26586)

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

    bpf: Reject variable offset alu on PTR_TO_FLOW_KEYS

    check_flow_keys_access() results in out of bounds access .For PTR_TO_FLOW_KEYS, check_flow_keys_access()     only uses fixed offfor validation. However, variable offset ptr alu is not prohibitedfor this ptr kind. So     the variable offset is not checked. (CVE-2024-26589)

    bpf: Fix re-attachment branch in bpf_tracing_prog_attach

    The following case can cause a crash due to missing attach_btf:

    1) load rawtp program2) load fentry program with rawtp as target_fd3) create tracing link for fentry     program with target_fd = 04) repeat 3 (CVE-2024-26591)
