CVSSv4: 6.8 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to an out-of-bounds read error within the sound/soc/qcom/lpass.h. A local user can perform a denial of service (DoS) attack.
41) Out-of-bounds read (CVE-ID: CVE-2026-72129)
CWE-ID: CWE-125 - Out-of-bounds read
CVSSv4: 7.1 [CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]
The vulnerability allows a remote user to cause a denial of service.
The vulnerability exists due to an out-of-bounds read in nvmet_rdma_use_inline_sg() and inline scatterlist handling in the NVMe target RDMA component when processing host-controlled inline data with a nonzero offset. A remote user can send crafted inline data offsets and lengths to cause a denial of service.
The issue can be triggered when inline_data_size is configured larger than PAGE_SIZE, and page-spanning in-bounds ranges may also cause the scatterlist to be under-counted.
42) Out-of-bounds read (CVE-ID: CVE-2026-72135)
CWE-ID: CWE-125 - Out-of-bounds read
CVSSv4: 8.4 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N]
The vulnerability allows a local user to disclose sensitive information and corrupt kernel memory.
The vulnerability exists due to an out-of-bounds read and out-of-bounds write in the TPM character device read path when processing positional read operations with a pending response. A local user can issue a crafted pread request with a large offset to disclose sensitive information and corrupt kernel memory.
The issue affects the sequential command/response TPM device interface after a command has left a response pending.
43) Improper access control (CVE-ID: CVE-2026-72136)
CWE-ID: CWE-284 - Improper Access Control
CVSSv4: 6.7 [CVSS:4.0/AV:L/AC:L/AT:N/PR:H/UI:N/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N]
The vulnerability allows a local privileged user to modify an xfrm interface across network namespace boundaries.
The vulnerability exists due to improper access control in xfrmi_changelink() when handling changelink requests for xfrm interfaces. A local privileged user can send a changelink request from one network namespace to rewrite an interface that lives in another network namespace to modify an xfrm interface across network namespace boundaries.
The issue occurs because the capability check was performed only against dev_net(dev) and not against the interface link network namespace.
44) Out-of-bounds write (CVE-ID: CVE-2026-72157)
CWE-ID: CWE-787 - Out-of-bounds write
CVSSv4: 8.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]
The vulnerability allows a remote attacker to corrupt memory.
The vulnerability exists due to an out-of-bounds write in tbnet_poll() when processing a multi-frame ThunderboltIP packet with a peer-supplied frame_count that exceeds the fragment array capacity. A remote attacker can send a specially crafted packet with 19 or more small frames to corrupt memory.
The issue occurs because the first frame is placed in the skb linear area while subsequent frames are added as page fragments.
45) Improper Initialization (CVE-ID: CVE-2026-72172)
CWE-ID: CWE-665 - Improper Initialization
CVSSv4: 6.7 [CVSS:4.0/AV:L/AC:L/AT:N/PR:H/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]
The vulnerability allows a local attacker to cause a denial of service.
The vulnerability exists due to uninitialized memory in struct pages for ZONE_DEVICE in mm/mm_init.c when hot-plugging DAX memory into an unoccupied subsection of an early section. A local attacker can hot-plug crafted DAX memory to cause a denial of service.
The issue occurs because the unoptimized boot memmap is reused for early sections while only a reduced number of struct pages are initialized, leaving remaining tail struct pages uninitialized.
46) Out-of-bounds write (CVE-ID: CVE-2026-72217)
CWE-ID: CWE-787 - Out-of-bounds write
CVSSv4: 8.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]
The vulnerability allows a remote attacker to cause memory corruption.
The vulnerability exists due to an out-of-bounds write in xdr_buf_to_bvec() when processing client-supplied RPC payload sizes. A remote attacker can send a specially crafted RPC request to cause memory corruption.
The out-of-bounds store can write one element past the end of the bio_vec array into adjacent slab memory, and the written length and offset fields are derived from client-controlled payload sizes.
47) Race condition (CVE-ID: CVE-2026-72221)
CWE-ID: CWE-362 - Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition')
CVSSv4: 8.2 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]
The vulnerability allows a remote attacker to cause a denial of service.
The vulnerability exists due to a race condition in svc_tcp_handshake() in the sunrpc server socket handling code when processing a TLS handshake callback during handshake cancellation. A remote attacker can trigger a TLS handshake timeout or interruption and cause concurrent handshake completion to corrupt the embedded swait_queue or tear down the connection to cause a denial of service.
The issue occurs when cancellation loses the race to handshake completion and the callback is still in flight.
48) Use-after-free (CVE-ID: CVE-2026-72222)
CWE-ID: CWE-416 - Use After Free
CVSSv4: 8.3 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:H/VA:H/SC:N/SI:N/SA:N]
The vulnerability allows a remote attacker to cause memory corruption.
The vulnerability exists due to a use-after-free in the sunrpc TLS handshake callback handling in svc_tcp_handshake() and svc_tcp_handshake_done() when a connection close overlaps an asynchronous TLS handshake. A remote attacker can trigger a connection close during the TLS handshake to cause memory corruption.
The issue is reachable on TLS-enabled NFS servers, and signal delivery during the interruptible wait can trigger the affected race window.
49) Use-after-free (CVE-ID: CVE-2026-72235)
CWE-ID: CWE-416 - Use After Free
CVSSv4: 8.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]
The vulnerability allows a remote attacker to cause a denial of service.
The vulnerability exists due to use-after-free in batadv_interface_rx() in the batman-adv soft interface code when processing received packets after a potential skb reallocation. A remote attacker can send a specially crafted packet to cause a denial of service.
50) Use-after-free (CVE-ID: CVE-2026-72282)
CWE-ID: CWE-416 - Use After Free
CVSSv4: 6.8 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]
The vulnerability allows a local user to cause a denial of service.
The vulnerability exists due to a use-after-free in kvm_io_bus_get_dev() and vgic_msi_to_its() when processing KVM MMIO bus device lookups for MSI addresses. A local user can trigger access to a matched device after the srcu lock has been dropped to cause a denial of service.
The issue occurs when the returned device matches only by address and is not the expected device type.
51) Integer overflow (CVE-ID: CVE-2026-72310)
CWE-ID: CWE-190 - Integer overflow
CVSSv4: 6.9 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N]
The vulnerability allows a remote attacker to disclose sensitive information.
The vulnerability exists due to an integer overflow in smb2_ioctl_query_info() when validating a PASSTHRU_FSCTL response payload from a malicious server. A remote attacker can send a specially crafted server response to disclose sensitive information.
The out-of-bounds read occurs during a later copy_to_user() operation after a wrapped offset-plus-length check passes.
