| Use of uninitialized variable in Tint in Google Chrome on on Android prior to 154.0.8037.57 allowed a remote attacker to read memory outside the sandbox via a crafted HTML page. (Chromium security severity: Medium) |
| Uninitialized resource in Media in Google Chrome on on Windows prior to 154.0.8037.92 allowed a remote attacker who had compromised the renderer process to read memory outside the sandbox via a crafted HTML page. (Chromium security severity: High) |

| Uninitialized resource in Skia in Google Chrome prior to 154.0.8037.92 allowed a remote attacker to obtain cross-origin data via a crafted HTML page. (Chromium security severity: High) |
| In the Linux kernel, the following vulnerability has been resolved:
hwmon: (ltc4282) Make sure clk_init_data is fully initialized
The clk_init_data structure contains several mutually-exclusive members
for different methods to specify the possible parents of a clock,
prompting drivers to initialize only the members they need. However,
not initializing all members may cause subtle issues, which are only
exposed when CONFIG_INIT_STACK_ALL_PATTERN or CONFIG_INIT_STACK_NONE is
enabled.
ltc428_clk_provider_setup() does not fill in any parent clocks, and
assumes that init.num_parents is NULL. However, the latter in
uninitialized, and thus may cause a crash.
Make sure all members are fully initialized, to fix such bugs, and to
avoid future breakage when converting drivers to a different method for
specifying the parents. |

| Use of uninitialized resource in Remote Desktop Client allows an authorized attacker to execute code over a network. |
| In the Linux kernel, the following vulnerability has been resolved:
ntfs: treat any nonzero dio zero-range return as an error
ntfs_dio_zero_range() returns either 0 or a negative errno from
blkdev_issue_zeroout(); it never returns a positive value. The
zeroing failure check in ntfs_attr_fallocate() therefore never fired,
so a failed zeroing operation was silently ignored: the loop kept
going, the newly allocated clusters were folded into initialized_size
and the write could succeed leaving stale on-disk data.
Treat any nonzero return as an error and abort the allocation. |

| In the Linux kernel, the following vulnerability has been resolved:
smb: client: avoid using uninitialized SIDs in cifs_posix_to_fattr()
cifs_posix_to_fattr() ignores the return value of posix_info_parse().
When a malformed POSIX directory entry is encountered (e.g. invalid
SID lengths from an untrusted server), posix_info_parse() returns -1
without populating the 'parsed' struct. The uninitialized stack
memory in parsed.owner and parsed.group is then passed to
sid_to_id(), which processes the garbage bytes and passes them to
request_key() to construct a SID string, potentially leaking kernel
stack contents to the userspace idmap daemon.
Fix this by checking the return value and skipping the SID-to-id
mapping when parsing fails. The remaining fattr fields (timestamps,
mode, etc.) are populated directly from the 'info' pointer so they
are unaffected. |
| In the Linux kernel, the following vulnerability has been resolved:
vxlan: initialize _md in vxlan_xmit_one()
If a VXLAN device is configured with both VXLAN_F_COLLECT_METADATA and
VXLAN_F_GBP, and a packet is transmitted through it using an external
ip_tunnel_info that lacks the IP_TUNNEL_VXLAN_OPT_BIT flag, md is left
pointing to the uninitialized _md stack variable:
if (test_bit(IP_TUNNEL_VXLAN_OPT_BIT, info->key.tun_flags)) {
if (info->options_len < sizeof(*md))
goto drop;
md = ip_tunnel_info_opts(info);
}
Because IP_TUNNEL_VXLAN_OPT_BIT is not set, md is not updated and remains
pointing to _md. Later, vxlan_build_skb() is called with md, which
eventually calls vxlan_build_gbp_hdr():
if (vxflags & VXLAN_F_GBP)
vxlan_build_gbp_hdr(vxh, md);
Inside vxlan_build_gbp_hdr(), md->gbp is read:
if (!md->gbp)
return;
gbp = (struct vxlanhdr_gbp *)vxh;
...
if (md->gbp & VXLAN_GBP_DONT_LEARN)
gbp->dont_learn = 1;
If the stack contains garbage, this causes:
1) VXLAN_HF_GBP flag to be spuriously set in the VXLAN header.
2) gbp->dont_learn and gbp->policy_applied to be set from stack bits.
3) gbp->policy_id to receive 16 bits of uninitialized kernel stack data,
leaking it onto the wire.
Fix this by zero-initializing _md. If IP_TUNNEL_VXLAN_OPT_BIT is not
present, md->gbp remains 0, and vxlan_build_gbp_hdr() returns early
without modifying the VXLAN header. |
| In the Linux kernel, the following vulnerability has been resolved:
accel: ethosu: Ensure SRAM region size matches job
It is possible for userspace to set the job SRAM size to 0, but then still
have SRAM accesses in the command stream. When the job SRAM size is 0,
setting the region base register is skipped and a stale base address from
a prior job is used.
Check the region size against the job's SRAM size instead of just the size
of the SRAM. The job's SRAM size was already checked against the total SRAM
size. |
| In the Linux kernel, the following vulnerability has been resolved:
smb/client: zero-initialize stack-allocated cifs_open_info_data
Stack-allocated cifs_open_info_data may contain random data.
This can make some fields have wrong value if they are not set later. |
| In the Linux kernel, the following vulnerability has been resolved:
nvme-fc: Do not cancel requests in io target before it is initialized
A new nvme-fc controller in CONNECTING state sees admin request timeout
schedules ctrl->ioerr_work to abort inflight requests. This ends up
calling __nvme_fc_abort_outstanding_ios() which aborts requests in both
admin and io tagsets. In case fc_ctrl->tag_set was not initialized we
see the warning below. This is because ctrl.queue_count is initialized
early in nvme_fc_alloc_ctrl().
nvme nvme0: NVME-FC{0}: starting error recovery Connectivity Loss
INFO: trying to register non-static key.
The code is fine but needs lockdep annotation, or maybe
lpfc 0000:ab:00.0: queue 0 connect admin queue failed (-6).
you didn't initialize this object before use?
turning off the locking correctness validator.

| In the Linux kernel, the following vulnerability has been resolved:
hwmon: (asus_rog_ryujin) Validate HID report lengths
rog_ryujin_raw_event() parses response headers and payload fields without
first checking that they are present in the received report. A short report
can therefore make the driver consume uninitialized bytes from the HID
transport buffer and expose them as sensor values through sysfs.
Validate the response header and the fields used by each response type
before parsing them. |
| In the Linux kernel, the following vulnerability has been resolved:
bnxt_en: Handle buffer allocation failure in bnxt_rx_ring_reset()
bnxt_rx_ring_reset() frees the ring buffers and then reallocates them,
ignoring the result.
bnxt_alloc_one_rx_ring() can fail in bnxt_alloc_one_tpa_info_data(), which
returns -ENOMEM on the first failed allocation and leaves the remaining
rxr->rx_tpa[] entries zeroed.
The error isn't propagated up, so the loop in bnxt_rx_ring_reset
continues and at the end the code re-enables TPA with partially
unallocated rx_tpa array.
This means that when the agg_id from hardware is mapped to a SW index in
rxr->rx_tpa[], an uninitialized slot can be chosen which would hand a
zero DMA address to the device.
Fix this by falling back to a global reset, which is what the existing
code already does when other functions fail, but unlike the other
failure cases this particular failure has to return because TPA can't
be re-enabled since the allocation failed. |
