usb: xhci: tegra: fix sleep in atomic call
When we set the dual-role port to Host mode, we observed the following
splat:

The function tegra_xusb_padctl_get_usb3_companion eventually calls
tegra_xusb_find_port and this in turn calls kasprintf which might sleep
and so cannot be called from an atomic context.
Fix this by moving the call to tegra_xusb_padctl_get_usb3_companion to
the tegra_xhci_id_work function where it is really needed. |
| In the Linux kernel, the following vulnerability has been resolved:
ionic: catch failure from devlink_alloc
Add a check for NULL on the alloc return. If devlink_alloc() fails and
we try to use devlink_priv() on the NULL return, the kernel gets very
unhappy and panics. With this fix, the driver load will still fail,
but at least it won't panic the kernel. |
| In the Linux kernel, the following vulnerability has been resolved:
wifi: rtw89: fix potential leak in rtw89_append_probe_req_ie()
Do `kfree_skb(new)` before `goto out` to prevent potential leak. |
| In the Linux kernel, the following vulnerability has been resolved:
wifi: mt76: mt7915: fix memory leak in mt7915_mcu_exit
Always purge mcu skb queues in mt7915_mcu_exit routine even if
mt7915_firmware_state fails. |
| In the Linux kernel, the following vulnerability has been resolved:
scsi: iscsi_tcp: Check that sock is valid before iscsi_set_param()
The validity of sock should be checked before assignment to avoid incorrect
values. Commit 57569c37f0ad ("scsi: iscsi: iscsi_tcp: Fix null-ptr-deref
while calling getpeername()") introduced this change which may lead to
inconsistent values of tcp_sw_conn->sendpage and conn->datadgst_en.
Fix the issue by moving the position of the assignment. |
| In the Linux kernel, the following vulnerability has been resolved:
io_uring: wait interruptibly for request completions on exit
WHen the ring exits, cleanup is done and the final cancelation and
waiting on completions is done by io_ring_exit_work. That function is
invoked by kworker, which doesn't take any signals. Because of that, it
doesn't really matter if we wait for completions in TASK_INTERRUPTIBLE
or TASK_UNINTERRUPTIBLE state. However, it does matter to the hung task
detection checker!
Normally we expect cancelations and completions to happen rather
quickly. Some test cases, however, will exit the ring and park the
owning task stopped (eg via SIGSTOP). If the owning task needs to run
task_work to complete requests, then io_ring_exit_work won't make any
progress until the task is runnable again. Hence io_ring_exit_work can
trigger the hung task detection, which is particularly problematic if
panic-on-hung-task is enabled.
As the ring exit doesn't take signals to begin with, have it wait
interruptibly rather than uninterruptibly. io_uring has a separate
stuck-exit warning that triggers independently anyway, so we're not
really missing anything by making this switch. |
| In the Linux kernel, the following vulnerability has been resolved:
wifi: rtw88: fix memory leak in rtw_usb_probe()
drivers/net/wireless/realtek/rtw88/usb.c:876 rtw_usb_probe()
warn: 'hw' from ieee80211_alloc_hw() not released on lines: 811
Fix this by modifying return to a goto statement. |
| In the Linux kernel, the following vulnerability has been resolved:
media: cx23885: Fix a null-ptr-deref bug in buffer_prepare() and buffer_finish()
When the driver calls cx23885_risc_buffer() to prepare the buffer, the
function call dma_alloc_coherent may fail, resulting in a empty buffer
risc->cpu. Later when we free the buffer or access the buffer, null ptr
deref is triggered.
This bug is similar to the following one:
https://git.linuxtv.org/media_stage.git/commit/?id=2b064d91440b33fba5b452f2d1b31f13ae911d71.
We believe the bug can be also dynamically triggered from user side.
Similarly, we fix this by checking the return value of cx23885_risc_buffer()
and the value of risc->cpu before buffer free. |
| In the Linux kernel, the following vulnerability has been resolved:
FS: JFS: Fix null-ptr-deref Read in txBegin
Syzkaller reported an issue where txBegin may be called
on a superblock in a read-only mounted filesystem which leads
to NULL pointer deref. This could be solved by checking if
the filesystem is read-only before calling txBegin, and returning
with appropiate error code. |
| In the Linux kernel, the following vulnerability has been resolved:
scsi: qla4xxx: Add length check when parsing nlattrs
There are three places that qla4xxx parses nlattrs:
- qla4xxx_set_chap_entry()
- qla4xxx_iface_set_param()
- qla4xxx_sysfs_ddb_set_param()
and each of them directly converts the nlattr to specific pointer of
structure without length checking. This could be dangerous as those
attributes are not validated and a malformed nlattr (e.g., length 0) could
result in an OOB read that leaks heap dirty data.
Add the nla_len check before accessing the nlattr data and return EINVAL if
the length check fails. |

| In the Linux kernel, the following vulnerability has been resolved:
ext4: remove a BUG_ON in ext4_mb_release_group_pa()
If a malicious fuzzer overwrites the ext4 superblock while it is
mounted such that the s_first_data_block is set to a very large
number, the calculation of the block group can underflow, and trigger
a BUG_ON check. Change this to be an ext4_warning so that we don't
crash the kernel. |

s390/dasd: Fix potential memleak in dasd_eckd_init()
`dasd_reserve_req` is allocated before `dasd_vol_info_req`, and it
also needs to be freed before the error returns, just like the other
cases in this function. |
| In the Linux kernel, the following vulnerability has been resolved:
HID: intel-ish-hid: Fix kernel panic during warm reset
During warm reset device->fw_client is set to NULL. If a bus driver is
registered after this NULL setting and before new firmware clients are
enumerated by ISHTP, kernel panic will result in the function
ishtp_cl_bus_match(). This is because of reference to
device->fw_client->props.protocol_name.
ISH firmware after getting successfully loaded, sends a warm reset
notification to remove all clients from the bus and sets
device->fw_client to NULL. Until kernel v5.15, all enabled ISHTP kernel
module drivers were loaded right after any of the first ISHTP device was
registered, regardless of whether it was a matched or an unmatched
device. This resulted in all drivers getting registered much before the
warm reset notification from ISH.
Starting kernel v5.16, this issue got exposed after the change was
introduced to load only bus drivers for the respective matching devices.
In this scenario, cros_ec_ishtp device and cros_ec_ishtp driver are
registered after the warm reset device fw_client NULL setting.
cros_ec_ishtp driver_register() triggers the callback to
ishtp_cl_bus_match() to match ISHTP driver to the device and causes kernel
panic in guid_equal() when dereferencing fw_client NULL pointer to get
protocol_name. |

VMCI: check context->notify_page after call to get_user_pages_fast() to avoid GPF

mt76: mt7921: fix kernel panic by accessing unallocated eeprom.data
The MT7921 driver no longer uses eeprom.data, but the relevant code has not
been removed completely since
commit 16d98b548365 ("mt76: mt7921: rely on mcu_get_nic_capability").
This could result in potential invalid memory access.
To fix the kernel panic issue in mt7921, it is necessary to avoid accessing
unallocated eeprom.data which can lead to invalid memory access.
Furthermore, it is possible to entirely eliminate the
mt7921_mcu_parse_eeprom function and solely depend on
mt7921_mcu_parse_response to divide the RxD header.

RDMA/bnxt_re: wraparound mbox producer index
Driver is not handling the wraparound of the mbox producer index correctly.
Currently the wraparound happens once u32 max is reached.
Bit 31 of the producer index register is special and should be set
only once for the first command. Because the producer index overflow
setting bit31 after a long time, FW goes to initialization sequence
and this causes FW hang.
Fix is to wraparound the mbox producer index once it reaches u16 max. |

netfilter: x_tables: fix percpu counter block leak on error path when creating new netns
Here is the stack where we allocate percpu counter block:
+-< __alloc_percpu
+-< xt_percpu_counter_alloc
+-< find_check_entry # {arp,ip,ip6}_tables.c
+-< translate_table
And it can be leaked on this code path:
+-> ip6t_register_table
+-> translate_table # allocates percpu counter block
+-> xt_register_table # fails
there is no freeing of the counter block on xt_register_table fail.
Note: xt_percpu_counter_free should be called to free it like we do in
do_replace through cleanup_entry helper (or in __ip6t_unregister_table).
Probability of hitting this error path is low AFAICS (xt_register_table
can only return ENOMEM here, as it is not replacing anything, as we are
creating new netns, and it is hard to imagine that all previous
allocations succeeded and after that one in xt_register_table failed).
But it's worth fixing even the rare leak. |
