| In the Linux kernel, the following vulnerability has been resolved:
igmp: Fix data-races around sysctl_igmp_qrv.
While reading sysctl_igmp_qrv, it can be changed concurrently.
Thus, we need to add READ_ONCE() to its readers.
This test can be packed into a helper, so such changes will be in the
follow-up series after net is merged into net-next.
qrv ?: READ_ONCE(net->ipv4.sysctl_igmp_qrv); |
| In the Linux kernel, the following vulnerability has been resolved:
tcp: Fix data-races around sysctl_tcp_migrate_req.
While reading sysctl_tcp_migrate_req, it can be changed concurrently.
Thus, we need to add READ_ONCE() to its readers. |
| In the Linux kernel, the following vulnerability has been resolved:
tcp: Fix a data-race around sysctl_tcp_notsent_lowat.
While reading sysctl_tcp_notsent_lowat, it can be changed concurrently.
Thus, we need to add READ_ONCE() to its reader. |
| In the Linux kernel, the following vulnerability has been resolved:
tcp: Fix data-races around sysctl_tcp_fastopen.
While reading sysctl_tcp_fastopen, it can be changed concurrently.
Thus, we need to add READ_ONCE() to its readers. |
| In the Linux kernel, the following vulnerability has been resolved:
tcp: Fix data-races around sysctl_tcp_fastopen_blackhole_timeout.
While reading sysctl_tcp_fastopen_blackhole_timeout, it can be changed
concurrently. Thus, we need to add READ_ONCE() to its readers. |
| In the Linux kernel, the following vulnerability has been resolved:
iavf: Fix handling of dummy receive descriptors
Fix memory leak caused by not handling dummy receive descriptor properly.
iavf_get_rx_buffer now sets the rx_buffer return value for dummy receive
descriptors. Without this patch, when the hardware writes a dummy
descriptor, iavf would not free the page allocated for the previous receive
buffer. This is an unlikely event but can still happen.

| In the Linux kernel, the following vulnerability has been resolved:
ipv4: Fix a data-race around sysctl_fib_multipath_use_neigh.
While reading sysctl_fib_multipath_use_neigh, it can be changed
concurrently. Thus, we need to add READ_ONCE() to its reader. |
| In the Linux kernel, the following vulnerability has been resolved:
ipv4: Fix data-races around sysctl_fib_multipath_hash_policy.

| In the Linux kernel, the following vulnerability has been resolved:
ip: Fix data-races around sysctl_ip_prot_sock.
sysctl_ip_prot_sock is accessed concurrently, and there is always a chance
of data-race. So, all readers and writers need some basic protection to
avoid load/store-tearing. |

udp: Fix a data-race around sysctl_udp_l3mdev_accept.
While reading sysctl_udp_l3mdev_accept, it can be changed concurrently.
Thus, we need to add READ_ONCE() to its reader. |

While reading sysctl_tcp_thin_linear_timeouts, it can be changed
concurrently. Thus, we need to add READ_ONCE() to its reader. |
| In the Linux kernel, the following vulnerability has been resolved:
tcp: Fix data-races around sysctl_tcp_recovery.
While reading sysctl_tcp_recovery, it can be changed concurrently.
Thus, we need to add READ_ONCE() to its readers. |
| In the Linux kernel, the following vulnerability has been resolved:
tcp: Fix a data-race around sysctl_tcp_early_retrans.
While reading sysctl_tcp_early_retrans, it can be changed concurrently.
Thus, we need to add READ_ONCE() to its reader. |
| In the Linux kernel, the following vulnerability has been resolved:
tcp: Fix data-races around sysctl_tcp_slow_start_after_idle.
While reading sysctl_tcp_slow_start_after_idle, it can be changed
concurrently. Thus, we need to add READ_ONCE() to its readers. |
| In the Linux kernel, the following vulnerability has been resolved:
x86/MCE/AMD: Fix memory leak when threshold_create_bank() fails
In mce_threshold_create_device(), if threshold_create_bank() fails, the
previously allocated threshold banks array @bp will be leaked because
the call to mce_threshold_remove_device() will not free it.
This happens because mce_threshold_remove_device() fetches the pointer
through the threshold_banks per-CPU variable but bp is written there
only after the bank creation is successful, and not before, when
threshold_create_bank() fails.
Add a helper which unwinds all the bank creation work previously done
and pass into it the previously allocated threshold banks array for
freeing.

| In the Linux kernel, the following vulnerability has been resolved:
bpf: Fix potential array overflow in bpf_trampoline_get_progs()
The cnt value in the 'cnt >= BPF_MAX_TRAMP_PROGS' check does not
include BPF_TRAMP_MODIFY_RETURN bpf programs, so the number of
the attached BPF_TRAMP_MODIFY_RETURN bpf programs in a trampoline
can exceed BPF_MAX_TRAMP_PROGS.
When this happens, the assignment '*progs++ = aux->prog' in
bpf_trampoline_get_progs() will cause progs array overflow as the
progs field in the bpf_tramp_progs struct can only hold at most
BPF_MAX_TRAMP_PROGS bpf programs. |

rtw89: cfo: check mac_id to avoid out-of-bounds
Somehow, hardware reports incorrect mac_id and pollute memory. Check index
before we access the array.

| In the Linux kernel, the following vulnerability has been resolved:
regulator: scmi: Fix refcount leak in scmi_regulator_probe
of_find_node_by_name() returns a node pointer with refcount
incremented, we should use of_node_put() on it when done.
Add missing of_node_put() to avoid refcount leak. |
| In the Linux kernel, the following vulnerability has been resolved:
firmware: arm_scmi: Fix list protocols enumeration in the base protocol
While enumerating protocols implemented by the SCMI platform using
BASE_DISCOVER_LIST_PROTOCOLS, the number of returned protocols is
currently validated in an improper way since the check employs a sum
between unsigned integers that could overflow and cause the check itself
to be silently bypassed if the returned value 'loop_num_ret' is big
enough.
Fix the validation avoiding the addition. |
| In the Linux kernel, the following vulnerability has been resolved:
RDMA/hfi1: Fix potential integer multiplication overflow errors
When multiplying of different types, an overflow is possible even when
storing the result in a larger type. This is because the conversion is
done after the multiplication. So arithmetic overflow and thus in
incorrect value is possible.
Correct an instance of this in the inter packet delay calculation. Fix by
ensuring one of the operands is u64 which will promote the other to u64 as
well ensuring no overflow. |
